Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an information management system for smoothly exchanging internal and external information in a medical diagnostic device.

[Technical background of the invention and its problems] The external output format of information in medical diagnostic equipment, such as an X-ray CT machine that obtains X-ray tomographic images, is as follows:
Images are recorded using images, Polaroid photographs, etc., and the format for exchanging information is
Images are recorded using MT and FD (floppy disc). The image recording by MT and FD is
Although recorded image data can be moved and has excellent storage stability, it is not easy to search for image data when the amount of recorded image data is large.

In ordinary hospitals, scan information for that day is often saved every time a test is completed, and at the same time records related to the test, such as how many scans were performed for each patient, are also kept in the form of documents.

However, records related to this inspection have not been given as much importance as image data, and have not been directly provided as input information to the apparatus in the past.

In addition, since the method of examination, the photographing position of the subject, etc. are generally determined in accordance with the doctor's written instructions, the operator must set up the apparatus each time in accordance with these instructions. In devices with improved operability, the imaging conditions (examination modes) are fixed in advance to simplify operation, but the device must be set each time according to the doctor's instructions. There is no difference.

[Object of the Invention] The present invention has been made in view of the above-mentioned circumstances, and provides a medical diagnostic device that can easily set imaging conditions and search for diagnostic information by effectively utilizing records related to examinations. The purpose is to provide a medical information management system.

[Summary of the Invention] The summary of the present invention for achieving the above object is to provide a storage device capable of storing imaging conditions and imaging methods used for automatic setting of a medical diagnostic device, and diagnostic information transferred from the medical diagnostic device. In a medical information management system that automatically configures a medical diagnostic device based on the information in this storage device and displays the information in the storage device as necessary, each time information is written to the storage device, this information is an external storage medium capable of recording search information indicating the storage location of the external storage medium; a storage medium input/output section for recording and reproducing the search information on the external storage medium; and a storage medium input/output section for outputting search information to the storage medium input/output section. and system control means for reading out information in the storage device according to the search information reproduced by the storage medium output section.

It has a recording section 4.
The recording of data on the external storage medium 2 and the reproduction of the recorded data are performed by the storage medium input/output unit 1 including, for example, a magnetic head. The system controller 6 can exchange imaging condition search data and diagnostic information search data with the system control means 6.

Next, the operation of the apparatus configured as described above will be explained with reference to the flowcharts shown in FIGS. 2 and 3.

First, an external storage medium 2 (for example, a magnetic card) created for each patient is set in the storage medium input/output section, and the operator inputs the information using the keyboard or the like.
Set the imaging conditions etc. on the X-ray CT device (step
S1). The contents of the settings such as the photographing conditions in this step S1 are stored in the storage device 5, and at the same time, for example, the serial number of the photographing conditions, etc. or the code corresponding to the contents of the photographing conditions, etc. are stored in the system control means 6 and the storage medium. The data is recorded as photographing condition search data in the first recording section 3 of the external storage medium 2 via the input/output section 1 (step S2). Next, depending on the shooting conditions etc. set in step S1,
The X-ray CT apparatus starts a CT scan, and the diagnostic information, that is, the scan information is transferred to the system control means 6 (step S3). The diagnostic information transferred to the system control means 6 is stored in the storage device 5, and at the same time, for example, the serial number of the diagnostic information or the code corresponding to the diagnostic information is stored in the system control means 6 and the storage medium input/output unit 1. The diagnostic information search data is recorded in the second recording unit 4 of the external storage medium 2 as diagnostic information search data (step S4). with this,
After the imaging of the patient is completed, the external storage medium 2 is stored in, for example, an external storage medium storage case (not shown), and is set in the storage medium input/output section 1 again for the next imaging or as needed. It is used for automatically setting conditions, searching for already collected diagnostic information, etc. The automatic setting of imaging conditions, search for diagnostic information, etc. will be described below with reference to the flowchart shown in FIG.

First, imaging condition search data and diagnostic information search data are reproduced from the external storage medium 2 set in the storage medium input/output section 1 (step S5), and these reproduced data are temporarily stored in the storage device 5 (step S5). Step S6). Next, assume that the operator selects either a search for imaging conditions or the like or a search for diagnostic information, and a request is generated. In other words, if the determination in step S7 is YES, the search for the photographing conditions, etc. is performed, and the search is performed in step S7.
If the judgment is NO and the step is
If the determination in S8 is YES, the diagnostic information will be searched (in addition, in step S7 and
If the determination in S8 is NO in either case, it means that the operator cannot make a determination; for example, there may be an abnormality in the setting of the external storage medium 2 or a system abnormality). Said step S7
If the determination is YES, that is, if the operator selects the search for the imaging conditions, etc., the items of the imaging conditions, etc. stored in the storage device 5 in the step S2 will be retrieved in the step S6. It is read out based on the photographing condition search data stored in the storage device 5 and displayed on the display means 8 (step S9). Next, the operator selects a desired photographing condition, etc. from among the items of photographing conditions displayed on the display means 8 (step 10). With this selection in step S10,
Details such as the corresponding photographing conditions are retrieved from the storage device 5 again and displayed on the display means 8 (step
S11). The operator can confirm, for example, the previous imaging conditions for the patient based on the display contents of the display means 8. In addition, when performing imaging of the patient again, in the selection step S10, select the conditions that correspond to or are closest to the current imaging conditions, display this on the display means 8, and set the imaging conditions, etc. It is determined whether or not it is necessary to make corrections (step S12). If the determination in step S12 is YES, that is, if it is determined that correction is necessary,
Make some corrections to the shooting conditions, etc. (step
S13). Next, when the operator presses, for example, an imaging condition setting button on the X-ray CT device, the step S13 is performed.
Based on the modified contents, a signal such as the imaging conditions is sent to the X-ray gantry bed etc. control unit 9, and the imaging conditions etc. are automatically set. In addition, the above steps
If the determination in S12 is NO, that is, if it is determined that there is no need to modify the photographing conditions, etc., the automatic adjustment of the photographing conditions, etc. in step S14 is performed without making any partial corrections in step S13. Settings are made.

Next, if the determination in step S8 is YES, that is, if the operator selects to search for diagnostic information, step S2 is performed.
For example, items of diagnostic information stored in the storage device 5 are read out based on the diagnostic information test data stored in the storage device 5 in step S6 and displayed on the display means 8 (step S15).
Next, the operator selects desired diagnostic information from, for example, the items of diagnostic information displayed on the display means 8 (step S16). By selecting this step S16, it is determined whether or not there is corresponding information (for example, an image) in the storage device 5 (step S16).
S17). If the determination in step S17 is YES, the corresponding diagnostic information is displayed on the display means 8 (step S18), and if the determination is NO, for example, the message "corresponding information does not exist" is displayed on the display means 8 (step S18). A message such as "No," is displayed on the display means 8.

In this way, the imaging condition search data and diagnostic information search data recorded in the external storage medium 2 created for each patient are used to set the imaging conditions for the second and subsequent imaging of the patient, and to set the imaging conditions for the previous imaging. It is possible to easily search for imaging conditions, etc. or diagnostic information.
