Abstract

PURPOSE:To store the picture information without losing various additional information on digital pictures by transferring the contents of the stored additional information to the processes of following stages by means of an identifier. CONSTITUTION:The identifier corresponding to the contents of the additional information is supplied to an input identifier register 11 when the contents of the necessary additional information are obtained from a picture information storing part 15. Then the identifier of the register 11 is compared with the identifier of an identifier register 18 through a comparator 12. If no coincidence is obtained between both identifiers, a pointer control register 13 reads the contents of a key information length register 17 with an instruction given from the comparator 12. Then the instruction is given to a pointer register 14 to extract the next key information out of the part 15. The identifier of the extracted key information is held by the register 18 and compared again with the input identifier through the comparator 12. This operation is repeated until the coincidence is obtained between identifiers. When the coincidence is obtained, the contents of this coincidence are extracted to an additional information contents register 19 for output.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an image information management method for storing and retrieving image information having a wide variety of image formats.

[Technical background of the invention and its problems]

In recent years, in the field of medical diagnosis, diagnosis using X-ray tomography has become increasingly popular.
With the advent of many T devices and diagnostic devices that utilize magnetic resonance phenomena, the variety of digital images in this field has increased significantly. The image information of these digital images is stored and searched using the additional information attached to the image data and stored at 9iffi.
It is.

This additional information includes various key information necessary for storage and retrieval, namely: (1) Image format information Key image data information such as image size and storage method.

■Patient information key Personal information such as patient's name and date of birth.

■Inspection information key Test data information such as test 8g, container, test date, etc.

0 diagnostic information key 1 ■ Diagnosis information such as the name of the doctor and diagnosis code.

■Other information keys are included as ~ boat fishing key information, and these key information are recorded in a key information section provided with a fixed length at a fixed location on the storage medium, as shown in Figure 3. It is common to However, the handling of additional information varies depending on the manufacturer and the type of VR device, so the code format of the additional information code, that is, the key information attached to the storage medium, has a wide variety of formats. . Therefore, for example, when comparing the content of supplementary information generated by one diagnostic device with the content of supplementary information generated by another diagnostic device, it is necessary to remember each format, and as a result, it is necessary to remember the format of each diagnostic device. The problem arises that as the number of cases increases, it becomes difficult to deal with them.

Furthermore, if new key information needs to be added to the supplementary information, it may be necessary to search for an empty space on the medium, or it may be necessary to change the length of the key information midway through the process. However, there are also problems with scalability, such as the inability to do so.

[Purpose of the invention]

The present invention has been made based on the above-mentioned circumstances, and an object of the present invention is to provide a new image information management method that can store incidental information related to a wide variety of digital images without losing any of it.

[1 Summary of the Invention] To achieve the above object, the present invention provides an image information management method for managing image information having a wide variety of image formats based on supplementary information of image data included therein. When storing incidental information of image data in an image information recording medium, the contents of the incidental information are stored together with a preset identifier, and the contents of the stored incidental information are transferred to a subsequent process by using the identifier. It's about doing what you can.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. First, a method for storing incidental information 9 will be described.

FIG. 1 is a diagram showing a storage method in the image information management method according to the present invention, FIG. 1(a) is a diagram showing the overall structure of image information, and FIG. FIG. 2C is a detailed diagram of a single key information section.

In FIG. 1, ``■'' is an auxiliary information section consisting of a file header part 2 and a key information section 3, and 4 is an image data information section in which image data is recorded.

The lengths of the supplementary information section 1 and the image data information section 4 are both formed as multiples of 512 bytes, for example.

File header part 2 is fixed at 16 bytes, and the file header part 2 is fixed at 16 bytes.
As shown in b), there is a fixed address 5 that can store 14-hide information, and a key information section length code 6 that indicates the information length of the entire key information section 3 (2-hide binary information can be stored). ). The key IF information unit 3 includes a plurality of small sections 3-, . 3-2, 3-3...3, and in each small section, worker key information, inspection key information, etc. are written, for example, as described above. And each key information subdivision 3-1゜: L, 3-3...3-, ,
Each identifier (2 hides) 3a and the key information length code (2 hides) indicating the length of each key information content
3b, and key information content 3c for recording, for example, a specific patient's name and date of birth. This key information content 3
The length of C can be changed as necessary.

Further, the identifier (2 bytes) 3a includes a group number 3d (1 byte), which is an identifier for major classifications such as patient information key and examination information key, and an identifier for minor classifications, such as name and date of birth. It shall consist of element number (1 hide) 3e.

Additional information of a wide variety of digital images is stored such that each key information content 3C has a predetermined common identifier 3a together with a key information length code 3b. As a result, digital images having a wide variety of key information can be efficiently managed using a common identifier. especially,
Depending on the type of digital image, the same key information may have different lengths, but according to this embodiment, it is possible to treat key information of different lengths as having the same idea. Furthermore, since the length of the key information content 3c can be changed, it is easy to add or change the content of the key information. Note that, if necessary, the key information length code 6 can be set as an information length that includes the image data information section 4 as well.

Next, a transfer means for outputting the contents of each key information stored as described above to the outside as necessary will be explained with reference to FIG. 2 as well. FIG. 2 is a block diagram showing a transfer means using the image information management method according to the present invention.

In FIG. 2, 11 is an input identifier register that holds an identifier input by a means not shown during a search, and 12 is an input identifier register that stores the identifier held in the input identifier register 11 and the identifier held in an identifier register 18, which will be described later. It is a comparator for comparison.

The signal from the comparison 812 is sent to the pointer control register 13 and the side information content register 16.

By the way, the above-mentioned identifier register 18 takes out and holds the identifier of certain key information in certain image information indicated by the pointer register 14 from the image information data storage section 15 which stores digital images by the above-mentioned storage method. Similarly, the length of the key information and the content of the key information are
Key information length register 17, key information content register 16
They are each taken out and held. Further, the pointer register 14 is controlled by a signal from the pointer control register 13. Reference numeral 19 denotes a supplementary information content register for output, which transfers the content of key information to the outside in response to a signal from the comparator 12 described above.

In order to obtain the contents of the necessary supplementary in FD (i.e., key information) from the image information storage unit 15, an identifier corresponding to the contents of the supplementary information (for example, the fool information key of the major classification) is inputted as an input identifier by means not shown. Input to register 11. The identifier input into the manual identifier register 11 is compared with an identifier in an identifier register I8, which will be described later, by a comparator 12. By the way, the identifier of the key information stored in the image information storage section 15 is retrieved and held in the identifier register 18 according to the instruction from the pointer register 14.

Similarly, the key information length register 17 and the key information content register 18 have the length and content of the key information extracted and held in accordance with instructions from the pointer register 14.

If the input identifier and retrieved identifier match, the contents of the incidental information content register 16 at that time (for example, the specific patient's name, date of birth, etc.) are outputted according to instructions from the comparator 12. The information is taken out to the supplementary information content register 19.

But if both of them don't lose at least once. In response to an instruction from the comparator 12, the pointer control register 13 reads the contents of the key information length register 17 and instructs the pointer register 14 to retrieve the next key information from the image information storage section 15. The retrieved identifier of the key information is held in the identifier register and compared again with the manually entered identifier by the comparator 12. If the two still do not match, the above-described operation is repeated until the input identifier and the information in the identifier register 18 match. However, when both sides lose once, the content of the information is taken out to the output supplementary information content register 19 as described above.

This not only allows you to easily retrieve the contents of the key information corresponding to any identifier, but also allows you to easily retrieve the information you need because the identifiers are divided into major classifications and minor classifications (3d, 3e). I can do it. In addition, the content of strip information generated by one diagnostic device can be easily compared with the content of additional information of other diagnostic devices using a common identifier, and furthermore, it does not depend on the order of storage. , there is no need to change the program.

〔Effect of the invention〕

As explained above, according to the present invention, the contents of supplementary information of a wide variety of digital images with different formats can be stored together with a preset identifier, and this identifier can be used when searching. It provides an image information management method that allows images to be easily stored and retrieved without any loss.
