Abstract

PURPOSE:To correspond to urgent inspection by storing picture data in an optical disk device when information peculiar to a reagent is judged to exist and storing picture data in a magnetic disk device when it is judged that it does not exist. CONSTITUTION:An online control part 14 compares information peculiar to a patient, which is extracted from incidental information, with judgement information stored in a memory 17 and judges the presence or absence of information peculiar to the patient. When it judges that it is not accurate information peculiar to the patient, it stores picture data in the magnetic disk device 12. When it judges that information peculiar to the patient is accurate, namely when it judges that there is information peculiar to the patient, it stores information in the optical disk device 13. Thus, correspondence to urgent inspection can be executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a medical image storage system for storing image data of a subject (usually a patient).

(Prior Art) A conventional medical image storage system is one in which an image storage device is connected online to various modalities (for example, an MRI device, an X-ray CT device, etc.).

Image data obtained by photographing a patient using various modalities is transferred to an image storage device with attached information including patient-specific information such as a patient name and a patient ID code. In the case of an emergency, the image data alone is often transferred to the image storage device without patient-specific information attached to the image data because of the urgency. In recent years, optical disk devices with a large storage capacity have been used as image storage devices, but unlike magnetic disk devices, it is difficult to rewrite data later.

(Problems to be Solved by the Invention) As described above, the conventional system stores image data in an optical disk device that is difficult to rewrite even in the case of an urgent case where there is no time to add patient-specific information.

For this reason, it was not possible to modify patient-specific information later, and the system lacked adaptability for emergency examinations.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a medical image storage system that eliminates the above-mentioned drawbacks and can also be used for emergency examinations.

[Configuration of the Invention (Means for Solving the Problems)] In order to achieve the above object, the present invention provides an image storage device that attaches subject-specific information to image data obtained by photographing a subject using a modality. In the medical image storage system, the image storage device determines the presence or absence of the subject-specific information in the image data transferred from the optical disk device and magnetic disk device that stores the image data and the modality, and determines that the image data is present. If it is determined that there is no image data, the image data is stored in the optical disk device, and if it is determined that there is no image data, the image data is stored in the magnetic disk device.

(for production) The operation of the system with the above configuration will be explained.

When photographing a subject that requires urgent examination and transferring the photographed image data to an image storage device, if there is no time to add subject-specific information to the image data, the data may be transferred without this subject-specific information. conduct.

The control means distributes the image data transferred from the modality to the optical disk device or magnetic disk device of the image storage device based on the presence or absence of subject-specific information in the image data.

(Example) An example system 1 of the present invention will be described in detail below with reference to the drawings.

This system 1 uses modalities 2 (2a, 2a,
2b, . . , and an image storage device 10 connected via an online interface 3.

The image storage device 10 includes a central processing unit 11 as a control means for controlling input and output of image data transferred from various modalities 2, and a magnetic disk device 12 and an optical disk device 13 that store image data. ing. The central processing unit 11 includes an online control unit 14, a magnetic disk control unit 15, an optical disk control unit 16, and a memory 17 that stores judgment information for determining whether or not patient-specific information is included in image data. are doing. The online control unit 14 receives image data and supplementary information attached to the image data from the various modalities 2, and extracts patient-specific information from the supplementary information. (The form of the supplementary information may be variable length information with an identifier such as ACR-NEMA, or may be a fixed form agreed upon with the modality 2). Furthermore, the online control unit 14 stores the patient-specific information extracted from the incidental information in the memory 1.
The presence or absence of patient-specific information is determined by comparing it with the judgment information stored in 7, and if it is determined that it is not correct patient-specific information, that is, it is determined that there is no patient-specific information, the image data is stored in the magnetic disk device 12. If it is determined to be correct patient-specific information, that is, if it is determined that patient-specific information exists, it is stored in the optical disk device 13.

An example of judgment information is the content of patient-specific information.

There is position information of characters to be compared, length information of nine characters, etc. For example, if a "?" mark is attached to the beginning of the additional information as judgment information, the online control unit 14 determines whether the position of that character is the beginning, and determines whether the character length is "1". Then, it is further determined whether the content is "?". If these conditions are satisfied, the online control unit 14
It is determined that this is not correct patient-specific information, and the image data is stored in the magnetic disk device 12.

The modality 2 includes an image display section (not shown) and also has an image reconstruction function, and the image data after this image reconstruction processing is transferred to the image storage device 10. The modality 2 also includes a keyboard (not shown) that allows input of patient name and patient ID information for each patient. With this keyboard operation, patient r
It is possible to read out and display previously captured image data on the image display unit by inputting D information, etc., and to perform an emergency examination and transfer image data without patient-specific information to the magnetic disk device. 12 to the display unit, and add the correct patient-specific information to the incidental information and display the optical disc device 1.
3 can be stored.

According to the above-described embodiment device 1 configured in this manner, image data can be stored simply by inputting judgment information during an emergency examination, and correct patient-specific information can be easily added to the image data later. Therefore, it is possible to provide a medical image storage system that can also handle emergency examinations.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and can be modified in various ways without changing the gist thereof.

[Effects of the Invention] According to the present invention detailed above, even if image data is transferred to an image storage device without attaching subject-specific information to the image data during an emergency examination, the subject-specific information is not attached to the image data later. Since this can be easily performed, it is possible to provide a medical image storage system that can also handle emergency examinations.
