Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an image information management device for managing image information having various image formats. In recent years, in the field of medical diagnosis, many diagnostic devices utilizing X-ray tomographic images, diagnostic devices utilizing the magnetic resonance phenomenon, etc. have appeared, and the types of digital images in this field have increased. It is increasing significantly. The image information of these digital images is usually stored and searched for using the additional information stored in association with the image data. The additional information includes various key information necessary for storage and retrieval, that is, information on image data such as an image format information key image size and a storage method. Patient information key Personal information such as patient name and date of birth. Inspection information key Inspection data information such as inspection equipment and inspection date. Diagnostic information key Diagnostic information such as the name of a doctor in charge and a diagnostic code. Other information keys are included as general key information, and these key information are preferably recorded in a key information section provided at a fixed location on a storage medium with a fixed length as shown in FIG. It is common. However, since the handling of the incidental information varies depending on the manufacturer or the type of diagnostic device, there are various types of incidental information codes set on the storage medium, that is, key information code formats. It has become a variety of formats. For example, to explain the patient name information of the patient information key, a certain diagnostic device sets the address of this information to 12 bytes from address 12 to 24 and assigns other information to addresses 0 to 11. On the other hand, the other diagnostic devices are set to 16 bytes from address 0 to address 16, and other information is allocated after address 16. In this example, the address range and the number of bytes to be designated are different, and the storage order is also different. Further, the format of the image data is often different for each diagnostic device, but the image format information key indicating this difference is also different for each diagnostic device like the above-mentioned patient information key. Therefore, for example, when comparing the contents of incidental information generated by a certain diagnostic device with the contents of incidental information generated by another diagnostic device, it is absolutely necessary to remember each format, and as a result, the type of diagnostic device The problem arises that it becomes difficult to deal with the increase in the number and numbers. Furthermore, when new key information has to be added as supplementary information, an unused area on the storage medium has to be searched for, and the length of the key information is halfway. When it is necessary to change, for example, in the patient name of the patient information key, when a patient who needs a large number of bytes of the name by entering katakana like foreigners comes to the diagnosis, In order to increase the number of bytes, it is necessary to shift the address of the key information after the key information of the patient name, and there is a problem in terms of expandability that the change cannot be easily performed. The present invention has been made in view of the above circumstances, and has been developed based on the above-mentioned circumstances. New image information capable of storing incidental information relating to various digital images without any loss.
The purpose is to provide a management device. [0009] To achieve the above object, according to an aspect of the present invention, based on the image information having a diverse range of data formats, the accompanying information of the image data included in the image information the image information management device for managing the, generation means for generating an identifier having a common format among contain information representing a classification of the biasing <br/> zone information, and the supplementary information generated by the generating means storage means for store have been identifier in the supplementary information length code <br/> co representing the supplementary information and the length of this supplementary information, for inputting an input identifier
Input means, and an input identification input by the input means
Characterized by comprising a search means for searching the image information by utilizing said identifier stored by the child and the storage unit. BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIG.
This will be described with reference to FIG. First, a method of storing the incidental information will be described. FIG. 1 is a diagram showing a storage method in an image information storage and retrieval apparatus according to the present invention, wherein FIG. 1 (a) is a diagram showing the configuration of the entire image information, and FIG. 1 (b) is a detailed diagram of a file header section. FIG. 3C is a detailed view of a single key information section. In FIG. 1, reference numeral 1 denotes an additional information section, which comprises a file header section 2 and a key information section 3, and 4 denotes an image data information section for recording image data. The lengths of the incidental information section 1 and the image data information section 4 are both 51, for example.
It is formed by a multiple of 2 bytes. The file header part 2 is fixed to 16 bytes, and as shown in FIG.
Fixed address 5 where byte information can be stored, and key information section 3
And a length code 6 (two-byte binary information can be stored) indicating the length of the key information indicating the entire information length. The key information section 3 is composed of a plurality of small sections _3-1 , _3-2 , _3-3, ... 3- _n , and each of the small sections contains, for example, patient key information and examination key information as described above. Remembered. Each of the key information subsections _3-1 , _3-2 , _3-3, ..., 3- _n includes a respective identifier (2 bytes) 3a and a key information length code (L) indicating the length of the key information content. 2 bytes) 3b
And key information 3c for recording a specific patient's name and date of birth, for example. The length of this key information content 3c can be changed as needed. Further, the identifier (2 bytes) 3a is, for example, a group number 3d (1 byte) that is a large classification identifier such as a patient information key / examination information key and a small classification identifier such as a name / date of birth. An element number (1 byte) 3e is assumed. [0012] A variety of digital image accompanying information 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 various kinds of key information can be efficiently managed by using a common identifier. In particular, the length of key information may differ for the same key information depending on the type of digital image, but according to the present embodiment, key information of different lengths can be treated as the same idea. In addition, 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. If necessary, the key information section length code 6 can be set as an information length including the image data information section 4. Next, a transfer means for outputting the contents of each key information stored as described above to the outside as necessary will be described with reference to FIG. FIG. 2 is a block diagram showing a transfer means using the image information storage / retrieval apparatus according to the present invention. In FIG. 2, reference numeral 11 is an input identifier register for holding an identifier input by means not shown at the time of retrieval, and 12 is an identifier held in the input identifier register 11 and an identifier held in an identifier register 18 described later. Is a comparator for comparing with. The signal from the comparator 12 is sent to a pointer control register 13 and an accompanying information content register 16. By the way, the above-mentioned identifier register 1
8 stores the pointer register 1 from the image information data storage unit 15 after the digital image is stored by the storage method described above.
An identifier of certain key information in certain image information designated by No. 4 is extracted and held. Similarly, the length of the key information and the content of the key information are stored in the key information length register 17,
Each key information content register 16 takes out and holds the key information. The pointer register 14 is controlled by a signal from the pointer control register 13. Reference numeral 19 denotes an output-related information register for transferring the contents of the key information to the outside in accordance with a signal from the comparator 12. In order to obtain the required supplementary information (ie, key information) contents from the image information storage unit 15, an identifier (for example, a major classification patient information key) corresponding to the supplementary information contents is obtained by means not shown. Input to the input identifier register 11. The identifier input to the input identifier register 11 is compared with an identifier of an identifier register 18 described later by the comparator 12. Incidentally, the identifier of the key information stored in the image information storage unit 15 is extracted and held in the identifier register 18 according to the instruction of the pointer register 14. Similarly, the key information length register 17 and the key information content register 16 extract and hold the length of the key information and the content of the information according to the instruction of the pointer register 14. If the input identifier and the retrieved identifier match, the contents of the auxiliary information content register 16 at that time (for example, a specific patient's name, date of birth, etc.) according to an instruction from the comparator 12. Is taken out to the additional information content register 19 for output. However, if they do not match, the comparator 12
The pointer control register 13 reads the contents of the key information length register 17 according to the instruction from the pointer register 1
4 is instructed to retrieve the next key information from the image information storage unit 15. The identifier of the extracted key information is held in the identifier register and compared with the identifier input by the comparator 12 again. And if they still do n’t match,
The above operation is repeated until the input identifier and the information in the identifier register 18 match. When the two coincide with each other, the content of the information is taken out to the output auxiliary information content register 19 as described above. Thus, not only can the contents of the key information corresponding to an arbitrary identifier be easily retrieved, but also the identifiers are classified into a large classification and a small classification (3d, 3e). Can be taken out. In addition, the content of the additional information generated from a certain diagnostic device and the content of the additional information of another diagnostic device can be easily compared using a common identifier. There is no need to change the. As described above, according to the present invention, the contents of incidental information of various digital images having different formats are stored together with a preset identifier, and this identifier is used at the time of retrieval. This makes it possible to treat key information with a different number of bytes as the same idea, furthermore, it is possible to easily add or change the content of the key information, and to easily search for images. it can.
