DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an endoscope filing apparatus which records a large number of image data in a plurality of recording means and manages the image data in a multiple manner.

[0002]

2. Description of the Related Art In recent years, an elongated insertion portion has been inserted into a body cavity,
2. Description of the Related Art An endoscope apparatus capable of observing a built-in body cavity device or the like on a monitor screen and performing an inspection or diagnosis using an imaging unit such as a solid-state imaging device is widely used.

In this endoscope device, an image file device is recorded so that an endoscope image picked up by an electronic endoscope or the like is recorded on a recording medium such as a magneto-optical disk and can be effectively used for later diagnosis and the like. There is a situation where the system is used as a system by being connected, and an easy-to-use system is desired.

Japanese Patent Application No. 61-302153, which is a first prior example of such a system, proposes a system which can share an analog image file device and a digital image file device. For example, images with high importance can be recorded on a digital image filing device, and images with low importance can be recorded on an analog image filing device.

Japanese Patent Application No. Sho 63-2 is a second prior example.
No. 70306 also proposes a system that can share an analog image file device and a digital image file device, and makes it possible to select a recording destination from an endoscope device for both file devices.

[0006] Further, Japanese Patent Application No. Hei 2-1 as a third preceding example.
No. 0228 proposes a system in which a magneto-optical disc on which images are digitally recorded in an endoscopy room can be transported to a remote conference room and read.

[0007]

In the first and second prior art examples, one image input device, one digital image file device and one analog image file device, and a file controller for controlling them are provided. 1
There is no description about the management of data when exchanging data between a plurality of systems, for example, when there is one set system and another set system coexists.

For this reason, when a plurality of systems coexist, for example, even if a previous endoscope image is searched to be used as reference material for diagnosis, image information between the systems is managed in a unified manner. As such, the endoscope image cannot be efficiently retrieved.

In the third prior example, there is a description that a magneto-optical disk recorded in an inspection room can be transported to a remote room, for example, a conference room and read there, but the number of inspections increases. Therefore, no information is recorded on the management of the magneto-optical disk when a large number of magneto-optical disks are present.

For this reason, for example, when an attempt is made to retrieve an endoscopic image of a certain patient, it is not known on which magneto-optical disk the image is recorded. It is necessary to check whether the data is recorded on the magneto-optical disk.

That is, in the prior example or the conventional example, particularly when there are a large number of recording media such as magneto-optical disks, they are not managed collectively, so that the system is not easy to use.

The present invention has been made in view of the above circumstances. By compressing an endoscope image by a plurality of methods and storing the compressed endoscope image in a plurality of storage means, the endoscope image can be multidimensionally managed. It is intended to provide an endoscope filing device.

In step S2, the data is converted into a communication format by the barcode adapter 24 and transmitted to the endoscope observation device 26 or the like. On the other hand, in S3, the patient name is input from the keyboard 54 and transmitted to the endoscope observation device 26 or the like. In S4 and S5, the endoscope observation device 26 assigns the ID No. to the input patient ID data, examination ID data, and patient name data. The header and the patient name header are added and transmitted to the image recording device 6. In S6, the input information identifying means 76 of the image recording device 6 sets the ID No. header,
The patient name header is identified, and the ID No. is determined in S7. In the case of the header, the process proceeds to S8, and in the case of the patient name header, the process proceeds to S9a. Further, the input information identification means 76 determines the ID No. in S8. The number of digits of the ID data is identified from the header. If the number of digits of the ID data is eight, the process proceeds to S9b, and if the number of digits of the ID data is sixteen, the process proceeds to S9c. In S9a to 9c, the input data is the patient I
It is determined whether the data is D data, examination ID data, or patient name data, and the process proceeds to S10. In S10, a database of patient data in the large-capacity hard disk 70 is searched based on the input data. In S11, the search result is transferred to the endoscope observation device 26. In S12, the search result is displayed on the display monitor 59 in the endoscope observation device 26 or the ultrasonic observation device 34, and the initial processing ends.

In the endoscope observation device 26 thus initialized, the endoscope 50 is inserted into the body cavity to start observation. When the operator grasps the desired observation site by the endoscope, as shown in FIG. 14, the image recording is started in S20,
In step S21, a release signal having information such as a recording method is input from the keyboard 54, and the release signal and the endoscope image signal are input to the CPU 58. Further, the communication I /
The release signal and the endoscope image signal are input to the image recording control device 72 in the image recording device 6 via the F60, and the A / D conversion of the endoscope image signal is performed and recorded in a memory (not shown).

Go to 9. In step S29, the examination data of the recorded image and the track No. of the analog recording device 64 that has performed analog recording are stored in the database of the patient data in the large-capacity hard disk 70. And the like and the file name of the digitally recorded file are recorded.
In S30, the end of the recording process is determined.
Returning to step 21, the processing is repeated, and when it is determined that the recording processing has been completed, the processing proceeds to S31 and ends.

The two types of reversibly and irreversibly compressed images recorded on the large-capacity hard disk 70 and the endoscope image signal recorded on the analog recording device 64 are obtained after the examination, by examining patient data and examination data. At the same time, the image is reproduced by the image reproducing device (A) 8 and the image reproducing device (B) and observed and diagnosed in detail. Also, a large-capacity hard disk 70
The irreversibly-compressed compressed image recorded in the large-capacity data recording device 1
The irreversible compressed image transferred and recorded in the storage device 2 and stored for a long period of time is stored and reproduced by the image reproduction device (A) 8 and the image reproduction device (B) together with the patient data and the examination data as needed.

Next, a method for long-term storage by transferring and recording a compressed image to the large-capacity data recording device 12 will be described.

As shown in FIG. 15, when the recording process is started in S40, in S41, the endoscope apparatus 2 shown in FIG.
The images from a to e or the ultrasonic endoscope devices 4 a to 4 c
The reversible image compression process and the irreversible image compression process are performed by the image compression device 66 via the image and data input / output device 62, the image recording control device 72, the server 74, and the image compression control device 68 in FIG. 68, and is recorded on the large-capacity hard disk 70 via the server 74.

Next, in S42, the image compression control device 68
Sets the copy flag of the database for managing the corresponding image in the server 74 with the contents set in advance in the image recording control device 72 (for example, conditions such as irreversible image). Depending on the processing state of the plurality of images, for example, among the images A, B, and C shown in Table 1, the copy flag is set to 1 because the image C is a non-reversible image and has not been copied.

[0042]

[Table 1] Subsequently, in S43, the image recording control device 72 monitors the states of the endoscope devices 2a to e and the ultrasonic endoscope devices 4a to 4c, and can perform a copy process, or, for example,
It is determined from the release interval or the like whether or not it is in the BUSY state or whether it is the end processing. In the end processing, the processing ends in S44. S
If it is determined in step 43 that the state is the BUSY state, step S41 is performed again.
And the work is repeated.

If it is determined in S43 that image copy processing is possible, and if there is an image for which the copy flag is set, then in S4
Step 5 is performed. In S45, the control device 78 of FIG. 9 shown in the large-capacity data recording device 12 of FIG. 1 copies the image with the copy flag set to the large-capacity recording medium 77 of FIG. For example, the image C in Table 1 is copied.

Next, at S46, the control device 78 lowers the copy flag of the image whose copy has been completed. For example, the copy flag is set to 0 as shown in the image B in Table 1, and the process returns to S43 to repeat the operation. Thus, the compressed image is stored in the large-capacity recording medium 77.

Next, the process of reproducing the compressed image stored as described above will be described.

The image is reproduced by the image reproducing device (A) 8 or the image reproducing device (B) 10. As shown in FIG. 16, when the reproduction process is started in S50, search conditions are input in S51 from the image reproduction instruction input units 88 and 100 in FIGS.

In S52, the image reproduction control devices 80 and 90 shown in FIGS. 10 and 11, respectively, refer to the database in the server 74 to determine whether or not the image to be searched is stored in the large-capacity hard disk 70. Make a judgment.
If the data is stored in the large-capacity hard disk 70, the flow shifts to S53. If it is not stored in the large-capacity hard disk 70, the process proceeds to S56.

In step S53, data is transferred from the large-capacity hard disk 70 to the image reproduction control device 80 or 90 which has issued a search request for a target image, and reproduction processing is performed. In S54, it is determined whether or not the reproduction processing is completed. If the reproduction processing is completed, the termination processing is performed in S55.

At S54, any trouble occurs.
The target image data is the large-capacity hard disk 70
When error processing such as not being transferred to the image reproduction control device 80 or 90 that made the search request is performed, the image reproduction control device 80 or 90 that made the search request
The process moves to S56.

In S56, the target image data is transferred from the large-capacity data recording device 12 to the image reproduction control device 80 or 90 which has requested the retrieval, and the reproduction process is performed. When the reproduction ends, an end process is performed in S55.

By performing the above control, the reproduction process is performed instead of the trouble process by the user, so that the reliability of the reproduction process can be improved.

Although digital and analog recording are selectively performed, they may be recorded simultaneously.

The communication between the endoscope device and the image recording device and between the host computer and the image recording device and the like may be performed by optically isolating.

Further, a password may be given to each operator according to the level of the operator (doctor, student, etc.) to use the endoscope file device 1, and patient data may be appropriately managed.

As described above, the endoscope file device 1 according to the present embodiment includes the endoscope devices 2a to 2e and the ultrasonic endoscopes 4a to 4e.
4c, the endoscope image signal and the ultrasonic image signal are recorded in an analog manner as appropriate, and two types of compressed images are recorded on the large-capacity hard disk 70 by lossless compression and irreversible compression. The recorded irreversibly-compressed compressed image is transferred to the large-capacity data recording device 12 for recording, stored for a long time, and subjected to lossless compression and irreversible compression recorded on the large-capacity hard disk 70 so that two types of compressed image and large Since the irreversible compressed image recorded in the capacity data recording device 12 and stored for a long time can be reproduced together with the patient data and the examination data as needed by the image reproducing device (A) 8 and the image reproducing device (B). The patient can manage the endoscope image plurally over the medium to long term and save the history of the patient, so that the diagnosis of the patient can be easily performed.
