Description

  The present embodiment as one aspect of the present invention relates to a medical image data processing apparatus and a medical image diagnostic apparatus for data processing of medical images.

  There is a case where a normal shutdown of the medical image diagnostic apparatus is not performed. In that case, at the next start-up, recovery of various DBs (data bases) held by the medical image diagnostic apparatus automatically runs. In that case, it takes a lot of time to recover the image DB. Therefore, the patient who needs the examination by the medical image diagnostic apparatus is made to wait, and the throughput is lowered. Also, in the case of emergency, the probability of saving the patient is reduced.

  In order to solve such a problem, there is a medical image diagnostic apparatus that performs only recovery related to a study after power-on to reduce the time required for recovery. However, since the number of studies per day and the number of generated images are enormous, the effect is weak.

  In addition, there is a technique for improving reliability by mirroring. However, the hardware is expensive because an extra double size hard disk is required. In addition, data registration speed is degraded. To prevent speed degradation, it is necessary to use more expensive hardware.

  In addition, there is a multiprocessing system that manages data in a plurality of DBs and increases the reliability of data storage (see, for example, Patent Document 1). This technique has a copy processing means, and has a copy management table and an unprocessed state management table, so that it can be recovered quickly.

  Further, there is a backup system having a backup PC and a database for a host computer and a database (see, for example, Patent Document 2). In this technique, the backup PC has a copy from the normal time, and the backup PC is substituted when the host computer fails. Compared to the prior art, it is possible to reduce the scale of the backup side and to simplify the switching operation to backup.

A case will be described in which only the first workflow DB 25a and the first raw DB 26a that do not require a specific time (load) are recovered at startup. In the X-ray CT apparatus 10, the second workflow DB 25 b and the second raw DB 26 b are not essential requirements, and thus are omitted in FIGS. 6 and 7.

Referring to FIG. 6, when the activation / recovery unit 31 and the activated unit 32 determine that recovery (index recovery or the like) of the first DB groups 25 a to 27 a is necessary, the second image is used instead of the first image DB 27 a. It has a function of controlling to use the DB 27b. When the startup / recovery unit 31 determines that the first DB group 25a to 27a needs to be recovered due to the fact that the past shutdown has not been normally performed at the time of startup, the startup / recovery unit 31 stores the first workflow DB 25a and the first raw DB 26a. recover, and the second image DB27b, activates the initiation reception unit 32. That is, when the activation / recovery unit 31 determines that the recovery of the first DB groups 25a to 27a is necessary, the startup / recovery unit 31 does not intentionally recover the first image DB 27a at this point.

  On the other hand, the activation / recovery means 31 has a function of activating the first DB groups 25a to 27a as usual when it is determined that the recovery of the first DB groups 25a to 27a is unnecessary.

And the acquired reconstructed image data is stored in the second image DB 27b activated by the activation / recovery means 31 (shown in FIG. 6). That is, the post-processing image generation unit 46 can reproduce a part of the reconstructed image data stored in the first image DB 27a that is not recovered in the second image DB 27b. Then, the post-processing image generation unit 46 is generated by the reconstructed image generation unit 44 in order to perform the non-executed post-processing image generation in accordance with a request from the execution request unit 42 (illustrated in FIG. 6), or Post-processed images are obtained by post-processing (image processing) the reconstructed image data acquired by using DICOM_Q / R and stored in the second image DB 27b activated by the activation / recovery means 31 (shown in FIG. 6).

For example, when reconstructed image generation corresponding to the patient ID “4444” of the workflow shown in FIG. 3 is performed, “uncompleted” in the corresponding part of the workflow illustrated in FIG. 3 is changed to “completed” and the workflow is updated.

  The workflow transfer unit 49 has a function of transferring the workflow updated and registered in the first workflow DB 25a by the workflow update registration unit 48 to the RIS 12 via the IF 24.

  The recovery request unit 50 has a function of making a recovery request for the first image DB 27a that has not been recovered each time the inspection by the scan control unit 43 is completed. The recovery request unit 50 acquires the execution contents of the reconstructed image generation and post-process image generation of the workflow stored in the first workflow DB 25a, and calculates the required size of the second image DB 27b that changes in time series. Then, the recovery request unit 50 calculates the recovery expiration date of the first image DB 27a based on the required size that changes in time series, and causes the display unit 29 to display it.

  FIG. 8 is a diagram illustrating an example of the recovery request message.

  9 to 11 are flowcharts showing the operation of the X-ray CT apparatus 10 of the first embodiment.

  Referring to FIG. 9, the X-ray CT apparatus 10 determines whether or not recovery of the first DB groups 25a to 27a is unnecessary at the time of activation (step ST1). If YES in step ST1, that is, if it is determined that the recovery of the first DB groups 25a to 27a is unnecessary at the time of activation, the X-ray CT apparatus 10 activates the first DB groups 25a to 27a, respectively ( Step ST2).

If YES in step ST14, that is, if it is determined that there is a shutdown instruction, the X-ray CT apparatus 10 shuts itself down (step ST15) and ends the operation. On the other hand, if NO in step ST14, that is, if it is determined that there is no shutdown instruction, the process returns to step ST3.

  When the determination in step ST1 is NO, that is, when it is determined that the recovery of the first DB groups 25a to 27a is necessary at the time of startup, the process proceeds to FIG. 10, and the X-ray CT apparatus 10 includes the first workflow DB 25a and the first workflow DB 25a. Each raw DB 26a is recovered (step ST21), and the second image DB 27b is activated (step ST22). The X-ray CT apparatus 10 transfers to the service center 14 via the IF 24 that the first image DB 27a needs to be recovered (step ST23).

  The X-ray CT apparatus 10 updates and registers the workflow registered in the first workflow DB 25a in accordance with the execution in steps ST26, ST28, ST30, ST31, and ST33 (step ST34). Moving to the description of FIG. 11, the X-ray CT apparatus 10 transfers the workflow updated and registered in the first workflow DB 25a in step ST34 to the RIS 12 via the IF 24 (step ST35).

  The X-ray CT apparatus 10 makes a recovery request for the first image DB 27a that has not been recovered by using a recovery request message (shown in FIG. 8) every time inspection is completed in step ST27 (step ST36). X-ray CT apparatus 10 determines whether or not there is a recovery instruction from input unit 28 operated by the operator (step ST37). If YES in step ST37, that is, if it is determined that there is a recovery instruction, the X-ray CT apparatus 10 executes recovery of the first image DB 27a (step ST38). Then, the X-ray CT apparatus 10 moves the reconstructed image data and post-processed image data of the second image DB 27b to the recovered first image DB 27a (step ST39).

  X-ray CT apparatus 10 determines whether or not there is a shutdown instruction from input unit 28 operated by the operator (step ST40). If YES in step ST40, that is, if it is determined that there is a shutdown instruction, X-ray CT apparatus 10 shuts itself down (step ST41) and ends the operation. On the other hand, if NO in step ST40, that is, if it is determined that there is no shutdown instruction, the process returns to step ST3 shown in FIG.

  If NO in step ST37, that is, if it is determined that there is no recovery instruction, the X-ray CT apparatus 10 determines whether there is a shutdown instruction from the input unit 28 operated by the operator (step ST42). ). If YES in step ST42, that is, if it is determined that there is a shutdown instruction, the X-ray CT apparatus 10 shuts itself down (step ST41) and ends the operation. On the other hand, if NO in step ST42, that is, if it is determined that there is no shutdown instruction, the process returns to the operation of step ST25 shown in FIG.

  Note that if the power supply is stopped due to a power failure or the like during steps ST1 to ST15 and ST21 to ST41, the X-ray CT apparatus 10 performs an abnormal shutdown.

  According to the X-ray CT apparatus 10 and the medical image data processing apparatus 21 of the first embodiment, when normal shutdown is not performed, a relatively long time (load) is required for recovery when the X-ray CT apparatus 10 is started. By not recovering the first image DB 27a, the next startup time can be greatly shortened with inexpensive hardware, and subsequent inspection, image generation, and image transfer can be performed without delay.

(Second Embodiment)
The schematic diagram of the medical image diagnostic apparatus of the second embodiment and its peripheral configuration is the “X-ray CT apparatus 10” of the schematic diagram showing the medical image diagnostic apparatus 10 of the first embodiment shown in FIG. 1 is the same as FIG. 1 except that “X-ray CT apparatus 10A” and “medical image data processing apparatus 21” are read as “medical image data processing apparatus 21A”, respectively, and thus description thereof is omitted. When it is determined that the first DB groups 25a to 27a need to be recovered, the medical image diagnostic apparatus according to the second embodiment uses only the first workflow DB 25a and the first raw DB 26a that require relatively little time (load) for recovery. This is a description of a case where recovery is attempted at startup and recovery at startup of the first workflow DB 25a fails. In the medical image diagnostic apparatus according to the second embodiment, the second raw DB 26b is not an essential requirement, and thus is omitted in FIGS.

  12 and 13 are block diagrams illustrating functions of the X-ray CT apparatus 10 according to the first embodiment.

  When the processor 22 of the X-ray CT apparatus 10A of the second embodiment executes the program, as shown in FIGS. 12 and 13, the X-ray CT apparatus 10 has DB switching means, that is, startup / recovery means (IPL). ) 31A and actuated means 32A. The activated unit 32A includes a maintenance request unit 41A, an execution request unit 42A, a scan control unit 43, a reconstructed image generation unit 44, a reconstructed image transfer unit 45, a post-process image generation unit 46, and a post-process image transfer unit 47. , Workflow update registration means 48A, workflow transfer means 49, recovery request means 50, recovery / migration means 51, reservation information acquisition means 52, workflow new registration means 53, and workflow correction registration means 54. In the X-ray CT apparatus 10A of the second embodiment, the second raw DB 26b is not an essential component.

  In the X-ray CT apparatus 10A of the second embodiment shown in FIGS. 12 and 13, the same means as those in the X-ray CT apparatus 10 of the first embodiment shown in FIGS. Is omitted.

Referring to FIG. 12, the activation / recovery unit 31A and the activated unit 32A control to use the second image DB 27b instead of the first image DB 27a when determining that the recovery of the first DB groups 25a to 27a is necessary. It has the function to do. If the startup / recovery means 31A determines that recovery of the first DB groups 25a to 27a is necessary due to the fact that the previous shutdown has not been performed normally at startup, the startup / recovery means 31A sets the first workflow DB 25a and the first raw DB 26a. Has a function to recover. Furthermore, start recovery unit 31A is at startup, it is determined to have failed to recover the first workflow DB25a, only the first raw DB26a recover, second workflow DB25b, second image DB27b, and the activation means 32A Has the function to start. That is, when the activation / recovery unit 31A determines that recovery of the first DB groups 25a to 27a is necessary, the startup / recovery unit 31A does not intentionally recover the first image DB 27a at this point.

On the other hand, when the activation / recovery means 31A determines that the recovery of both the first workflow DB 25a and the first raw DB 26a is successful at the time of activation, as described in the X-ray CT apparatus 10 of the first embodiment, the second image DB27b and the activation means 32 has a function to start (shown in FIGS. 6 and 7).

  The activated unit 32A operates when the activation / recovery unit 31A determines that the recovery of the first DB groups 25a to 27a is necessary and the recovery of the first workflow DB 25a fails. The maintenance requesting unit 41A of the activated unit 32A determines that the recovery of the first DB group 25a to 27a is necessary by the activation / recovery unit 31A and fails to recover the first workflow DB 25a via the IF 24. It has a function of transferring to the service center 14.

  The reservation information acquisition unit 52 has a function of acquiring reservation information from the RIS 12 via the IF 24. The reservation information acquisition unit 52 acquires reservation information including information on the inspection, image generation, and image transfer that have not been performed.

  The new workflow registration unit 53 has a function of using DICOM_Q / R to make a search query for reconstructed image data and post-processed image data to the reconstructed image transfer destination and post-process image transfer destination. Then, the new workflow registration means 53 searches the reservation information acquired by the reservation information acquisition means 52, the post-processing type corresponding to the inspection type of the reservation information (based on the inspection type-post-processing table shown in FIG. 2), the search A workflow is generated by associating the inspection, image generation, and image transfer execution information based on the inquiry result, and the workflow is newly registered in the second workflow DB 25b activated by the activation / recovery means 31A. It has a function. The newly registered workflow may be displayed on the display unit 29 (shown in FIG. 7).

  FIG. 14 is a diagram illustrating an example of a workflow newly registered in the second workflow DB 25b.

  FIG. 14 is a diagram showing an example of a workflow that is newly registered in the second workflow DB 25b after the X-ray CT apparatus 10A is activated. As shown in FIG. 14, the workflow newly registered in the second workflow DB 25 b includes reservation information, a post-processing type corresponding to the inspection type of the reservation information, reconstructed image generation, reconstructed image transfer, and post-processing. Image generation and post-processing image transfer are associated with each other.

  Here, when DICOM_Q / R is used to make a search inquiry to the reconstructed image transfer destinations such as the image server 11 and the WS 13 and it is determined that the reconstructed image data is stored, the workflow registered in the second workflow DB 25b. “Done” indicating that the reconstructed image generation and the reconstructed image transfer are performed is associated with the corresponding part. Similarly, when DICOM_Q / R is used to make a search inquiry to the post-processing image transfer destination such as the image server 11 and WS 13, and the post-processing image data is determined to be stored, the workflow registered in the second workflow DB 25b. “Done” indicating that the post-processing image generation and post-processing image transfer are performed is associated with the corresponding part. On the other hand, “not yet” indicating non-execution is associated with other parts of the reconstructed image generation, reconstructed image transfer, post-process image generation, and post-process image transfer of the workflow registered in the second workflow DB 25b. It is done.

  According to the workflow shown in FIG. 3, since the reconstructed image generation corresponding to the patient ID “3333” is “completed”, the reconstructed image data corresponding to the patient ID “3333” is stored in the first image DB 27a. . Further, according to the workflow shown in FIG. 3, the reconstructed image transfer corresponding to the patient ID “3333” is “not yet”. Therefore, according to the workflow shown in FIG. 3, for the patient ID “3333”, the reconstructed image stored in the first image DB 27a may be transferred. However, if it is determined that the recovery of the first DB group 25a to 27a is necessary and the recovery of the first workflow DB 25a fails, the reconstructed image generation corresponding to the patient ID “3333” is generated as shown in the workflow shown in FIG. Is unknown, so it is set as “not yet”. This is because the reconstructed image data has not been transferred.

  Returning to the description of FIG. 12, the execution requesting unit 42A refers to the workflow registered in the workflow DB set 25, and performs the unexecuted inspection and reconstructed image with respect to the simple data recovery unit (units 43 to 47). A function for requesting generation, reconstructed image transfer, post-process image generation, and post-process image transfer; The execution request unit 42A refers to a workflow (shown in FIG. 14) newly registered in the second workflow DB 25b activated by the activation / recovery unit 31A. Here, the execution requesting unit 42A refers to the scheduled interpretation completion date of the workflow when requesting execution of unexecuted inspection, reconstructed image generation, reconstructed image transfer, post-process image generation, and post-process image transfer. It is preferable to perform the execution requests in order from the oldest.

  Moving to the description of FIG. 13, the workflow update registration means 48A updates and registers the workflow registered in the second workflow DB 25b activated by the activation / recovery means 31A (shown in FIG. 12) according to the implementation by the means 43 to 47. It has the function to do. For example, when reconstructed image generation corresponding to the patient ID “4444” of the workflow shown in FIG. 14 is performed, “not yet” in the corresponding part of the workflow shown in FIG. 14 is changed to “done”, and the workflow is updated.

  Next, the operation of the X-ray CT apparatus 10A of the second embodiment will be described with reference to FIG.

  15 to 17 are flowcharts showing the operation of the X-ray CT apparatus 10A of the second embodiment.

  Referring to FIG. 15, the X-ray CT apparatus 10A determines whether or not recovery of the first DB groups 25a to 27a is unnecessary at the time of activation (step ST50). If YES in step ST50, that is, if it is determined that recovery of the first DB groups 25a to 27a is unnecessary at the time of startup, the process proceeds to the operation of step ST2 shown in FIG.

  On the other hand, if the determination in step ST50 is NO, that is, if it is determined that the first DB group 25a to 27a needs to be recovered at the time of startup, has the X-ray CT apparatus 10A successfully recovered the first workflow DB 25a? It is determined whether or not (step ST51). If YES in step ST51, that is, if it is determined that the recovery of the first workflow DB 25a is successful at the time of activation, the X-ray CT apparatus 10A proceeds to the operation of step ST21 in FIG.

  On the other hand, if the determination in step ST51 is NO, that is, when it is determined that the recovery of the first workflow DB 25a has failed at the time of startup, the process proceeds to FIG. 16 and the X-ray CT apparatus 10A recovers the first raw DB 26a. (Step ST52), the second workflow DB 25b and the second image DB 27b are activated (Step ST53). The X-ray CT apparatus 10A transfers to the service center 14 via the IF 24 that the first image DB 27a needs to be recovered (step ST54).

  The X-ray CT apparatus 10A acquires reservation information from the RIS 12 via the IF 24 (step ST55). The X-ray CT apparatus 10A uses DICOM_Q / R to make a search query for the reconstructed image data to the reconstructed image transfer destination to obtain the reconstructed image data. The second image DB 27b activated by ST53 is stored (step ST56). That is, in step ST56, the X-ray CT apparatus 10A can reproduce a part of the reconstructed image data stored in the first image DB 27a that is not recovered in the second image DB 27b.

  The X-ray CT apparatus 10A uses DICOM_Q / R to make a search query for the reconstructed image data and post-processed image data to the reconstructed image transfer destination and post-process image transfer destination, and the reservation acquired in step ST55. Information, post-processing type corresponding to the inspection type of the reservation information (based on the inspection type-post-processing table shown in FIG. 2), and information on the execution of the inspection, image generation, and image transfer based on the result of the search query The associated workflow (shown in FIG. 14) is generated, and the workflow is newly registered in the second workflow DB 25b activated in step ST53 (step ST57).

  The X-ray CT apparatus 10A refers to the workflow (shown in FIG. 14) registered in step ST57 in the second workflow DB 25b activated in step ST53, and has not performed inspection, reconstructed image generation, and reconstructed image. Request is made to perform transfer, post-process image generation, and post-process image transfer (step ST58).

  The X-ray CT apparatus 10A controls the operation of the imaging unit 20 to collect raw data (step ST59) and performs the raw data according to the request at step ST52 in order to perform an unperformed inspection according to the request at step ST58. It is stored in the recovered first raw DB 26a (step ST60). Alternatively, the X-ray CT apparatus 10A performs image reconstruction based on the raw data stored in step ST60 in order to perform reconstruction image generation that has not been performed in accordance with the request in step ST58, and generates reconstructed image data. Generated (step ST61), the reconstructed image data is stored in the second image DB 27b activated in step ST53 (step ST62). Alternatively, the X-ray CT apparatus 10A uses the reconstruction image data stored in step ST62 to the image server 11 or the WS 13 via the IF 24 in order to perform the unconstructed reconstruction image transfer in accordance with the request in step ST58. Transfer (step ST63). Alternatively, the X-ray CT apparatus 10A performs post-processing (image processing) on the reconstructed image data stored in step ST56 or ST62 in order to perform unprocessed post-processing image generation in accordance with the request in step ST58. Post-processed image data is generated (step ST64), and the post-processed image data is stored in the second image DB 27b activated in step ST53 (step ST65). Alternatively, the X-ray CT apparatus 10A, in accordance with the request at step ST58, transfers the post-processed image data stored at step ST65 to the image server 11 or WS 13 via the IF 24 in order to perform the post-processed image transfer that has not been performed. Transfer (step ST66).

  The X-ray CT apparatus 10A updates and registers the newly registered workflow in the second workflow DB 25b in accordance with the operations in steps ST59, ST61, ST63, ST64, and ST66 (step ST67). Moving to the description of FIG. 17, the X-ray CT apparatus 10A transfers the workflow updated and registered in the second workflow DB 25b in step ST67 to the RIS 12 via the IF 24 (step ST68).

  The X-ray CT apparatus 10A makes a recovery request for the unrecovered first image DB 27a by using a recovery request message (shown in FIG. 8) every time the examination is completed in step ST59 (step ST69). X-ray CT apparatus 10A determines whether or not there is a recovery instruction from input unit 28 operated by the operator (step ST70). If YES in step ST70, that is, if it is determined that there is a recovery instruction, the X-ray CT apparatus 10A executes recovery of the first image DB 27a (step ST71). Then, the X-ray CT apparatus 10A shifts the reconstructed image data and post-processed image data of the second image DB 27b to the recovered first image DB 7a (step ST72).

  X-ray CT apparatus 10A determines whether or not there is a shutdown instruction from input unit 28 operated by the operator (step ST73). If YES in step ST73, that is, if it is determined that there is a shutdown instruction, X-ray CT apparatus 10A shuts itself down (step ST74) and ends the operation. On the other hand, if NO in step ST73, that is, if it is determined that there is no shutdown instruction, the process returns to the operation of step ST3 shown in FIG. 9 (however, in the X-ray CT apparatus 10A of the second embodiment, the first workflow DB 25a is recovered). (It is assumed that “first workflow DB 25a” in steps ST3 to ST15 shown in FIG. 9 is replaced with “second workflow DB 25b”.)

  If NO in step ST70, that is, if it is determined that there is no recovery instruction, the X-ray CT apparatus 10A determines whether there is a shutdown instruction from the input unit 28 operated by the operator (step ST75). ). If YES in step ST75, that is, if it is determined that there is a shutdown instruction, X-ray CT apparatus 10A shuts itself down (step ST74) and ends the operation. On the other hand, if NO in step ST75, that is, if it is determined that there is no shutdown instruction, the operation proceeds to step ST58 shown in FIG.

  Note that if the power supply is stopped due to a power failure or the like in the middle of steps ST50 to ST74, the X-ray CT apparatus 10A performs an abnormal shutdown.

  According to the X-ray CT apparatus 10A and the medical image data processing apparatus 21A of the second embodiment, when normal shutdown is not performed, a relatively long time (load) is required for recovery when the X-ray CT apparatus 10A is activated. By not recovering the first image DB 27a, even if the recovery of the workflow DB fails, the next startup time can be greatly shortened with inexpensive hardware, and subsequent inspections, image generation, and image transfer can be performed without delay. it can.
