Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for filing medical image information, and more specifically, the present invention relates to a method for filing medical image information, and more specifically, the present invention relates to a method for filing medical image information. The present invention relates to a filing method for medical image information that is efficiently recorded and stored on a recording medium.

[Background of the Invention] In the medical field, it has been common practice to record radiographic image information on X-ray film. In this case, the X-ray film on which image information is recorded is required to be stored for at least five years, and a huge amount of X-ray film will be stored during that time. Therefore, facilities such as hospitals must have sufficient space to store X-ray films. Further, in order to preserve such an X-ray film well for a long period of time, the XvA film must be stored in a state isolated from moisture and external light, and countermeasures for this purpose are also required.

Therefore, the present applicant uses a stimulable phosphor to obtain image information as a radiation transmitted image of a subject, outputs the image information as a visible image to a recording material such as a film, a CRT, etc., and also outputs the image information as a visible image to a recording material such as a film, a CRT, etc. We have filed a patent application for a radiation image information processing system that is configured to record and store search information on a medium and retrieve desired image information based on the search information as needed (Special Training Room No. 61-151905).
No. etc.). Here, the term stimulable phosphor refers to radiation (X-rays, α
rays, β rays, γ rays, electron beams, ultraviolet rays, etc.), some of this radiation energy is accumulated, and later by irradiation with excitation light such as visible light, stimulated luminescence occurs according to the accumulated energy. A phosphor that

In this case, in the system, image information can be recorded and stored on a large-capacity recording medium such as an optical disk, and desired image information can be quickly retrieved based on search information and output as a visible image, which is useful for management purposes. , or extremely effective for medical diagnosis.

By the way, in medical facilities such as hospitals, not all of the four image information is created by the above-mentioned system, but a large amount of information is also created by other modalities such as, for example, a CT device, an MR device, and an X-ray imaging device. In this case, it is desirable that the image information created by the other modality be stored in the same format as the image information obtained by the system described above. In other words, if all image information is stored along with its search information on a large-capacity recording medium such as an optical disk, it will be easier to manage it and the search efficiency will be improved when retrieving desired image data. Very clear.

Therefore, it is conceivable to photoelectrically read image information obtained by a device other than the above system using a scanner or the like, and record the image information together with the search information on an optical disk or the like.

In this case, the search information is generally input by an operator from a keyboard etc. in conjunction with inputting the image information onto an optical disc, etc., but there is a risk of human error occurring when inputting this information. There is. Further, the input work of image information and the input work of search information related to the image information need to be performed in parallel, and thus a plurality of workers are required for the work. Moreover, since image information and search information cannot be input individually and continuously, there is a disadvantage that efficient input work cannot be performed.

[Object of the Invention] The present invention has been made in order to overcome the above-mentioned disadvantages, and is to read image information recorded on a record carrier such as a film together with search information recorded on a label, sheet, etc. to create an optical disc.

It is characterized by being recorded and saved.

Furthermore, when image information recorded on a recording medium such as a film is recorded and saved on a recording medium such as an optical disk, the present invention reads the search information from the record carrier carrying the search information related to the image information and generates the search data. Next, a record carrier carrying image information related to the search information is scanned to create image data, and the image data is further recorded and saved on a recording medium together with the search data.
