[Formation for carrying out the invention]

Fig. 1 is a block diagram showing a preferred embodiment of a bone density measuring device as a medical device of the present invention. This bone density measuring device is installed in a hospital or the like, and measures the bone density (bone salt amount) of the subject.

In the first embodiment, the bone density measuring apparatus roughly includes a measuring unit 10 and an arithmetic unit 12. First, the measurement unit 10 will be described. The measuring unit 10 has a bed 14 on which the inspector 16 is placed. In the case of performing lumbar spine measurement, the position of the subject on the bed 14 is determined such that the lumbar vertebrae to be measured enters the irradiation region (analysis region) of the X-ray beam.

An X-ray generating unit 18 is disposed below the bed 14 and has an X-ray generating tube 20. This X-ray generation tube 20 is supplied with electric power from a high voltage source 26 (HV).

On the other hand, the X-ray detecting unit 24 is provided above the inspected person accommodation space set on the upper side of the bed 14 . In the present embodiment, an X-ray beam 22 having a fan beam shape is formed by the X-ray generation tube 20 and a collimator (not shown). The X-rays thus irradiated and passed through the subject (inspector 16) are detected by the X-ray detecting unit 24. The X-ray detecting unit 24 is, for example, a plurality of X-ray sensors arranged in a single element. It can also be illuminated as a pencil beam or a cone beam. Further, an X-ray sensing array of a secondary element can also be utilized.

In the present embodiment, the X-ray generation unit 18 and the X-ray detecting unit 24 are driven by a transport unit not shown, for example, by being scanned in the axial direction of the back bone or in the vertical direction of the paper. Further, in the case of the Dual Energy X-ray Absorptiometry method, high-energy X-rays and low-energy X-rays are alternately irradiated, and secondary element detection data corresponding to the respective X-rays are obtained.

Next, the calculation unit 12 will be described. The bone density image forming unit 28 is based on self-X-rays The detection data output by the detecting unit 24 forms a module for the bone density image of the subject. The data of the formed bone density image is displayed on the display unit 40 by the display processing unit 30.

In the present embodiment, the control unit 32 has functions as the confirmation video generation unit 34, the step management unit 36, and the video customization unit 38. These functions are essentially software-implemented. The confirmation image generation unit 34 generates a confirmation image including the check list in the respective plural number confirmation step incorporated in the plurality of steps. The image is sent to the display unit 40 by the display processing unit 30, and the image is displayed on the screen of the display unit 40. The step management unit 36 manages the modules that are executed in a series of steps from the input step to the output step, in particular, the confirmation step that is executed after the execution of the steps of each entity, and confirms the input of all the inspection items (or the necessary number). Completion is performed as a condition, and control is performed to allow the steps of the next entity to be carried out. That is, basically, the execution of the next step is restricted when the confirmation of all the items of the check list is not completed. By such control, it is judged whether the result of the execution is appropriate or not after the end of each physical step. The image customization unit 38 is a module for arranging a confirmation image, and a module for performing a process of customizing the display aspect for a specific sentence or a part of an article that displays each of the inspection items constituting the table. For example, in any part of the article, the attributes such as gradation, size, and color can be freely changed. That is, the display aspect of the checklist can be changed. The image customization unit 38 functions as a display control unit.

In the present embodiment, regarding the image customization processing, an examiner or a user may specify any portion (for example, a sentence) in the check list, or an arbitrary display aspect or display condition may be set in the portion. Such conditions are stored in the memory unit 44, and such information is referred to when confirming the generation of the image. Accordingly, a confirmation image containing a customized checklist is generated.

For each examiner, it is expected that it can be constructed in such a way that it can memorize the custom conditions of the examiner. That is, for the memory part, the memory of the complex information corresponding to the plural examiner is memorized by the plural In the customization information, the customized information of the specific examiner corresponding to the current inspection is referred to, and the customized processing can be performed based on this. Further, it is also necessary to register the composition of the customized conditions in response to the combination of the examiner and the examinee. In the display of each checklist, if the examiner specifies the display mode specified by the examiner itself, the check items in the checklist can be recognized and easily identified, and the check can be performed without error and promptly. operation. Incidentally, in the customization process of the present embodiment, only the display aspect is allowed to be changed, and the change of the article content itself of the inspection item is prohibited. Of course, it can be configured to allow changes in the content of the article. Further, as will be described later, in the present embodiment, in the display of the check list, the display in the first stage is not displayed to the extent of the detailed description, but the detailed operation of each inspection item can be displayed by performing the designated operation. Information appears on the screen. Details on this point are as follows. Such detailed descriptions are also expected to be able to be constructed in a manner that is customizable in the manner in which they are displayed.

The input unit 42 is constituted by a keyboard or the like, and input such as customization conditions is performed using the input unit 42. The customization condition is registered in the memory unit 44. The display processing unit 30 is provided with an image synthesizing function or a color processing function. A bone density image or a confirmation image is displayed on the screen of the display unit 40.

The second diagram schematically shows an example of the confirmation screen 48 (confirmation display) displayed on the display screen 46. The confirmation screen 48 includes a checklist having a plurality of items 50 (inspection item documents). Each item 50 has an inspection frame 52, and the inspection box 52 is input by the examiner for confirmation by an operation of a mouse or the like. The image 54 is set corresponding to each item 50, and when the operation-specific image 54 is pressed, the pop-up display 56 (bounce window) corresponding to the specific image 54 is displayed on the screen. This bounce display 56 contains a detailed description of the corresponding designated image 54. That is, in any item, more detailed information becomes necessary, and an image corresponding to the item is operated, and a detailed explanation appears on the screen. As mentioned above, regarding the content of each item 50, in particular, the display aspect can be customized and jumped out. Display 56 can also customize this display as necessary. The jump-out display 56 is disappeared from the screen via the designated input.

In the present embodiment, as will be described below, the step of executing the confirmation is performed in the step of each entity, and in each confirmation step, a check list including a plurality of items for confirming the result of the adjacent entity step is displayed. The details of this are as follows.

In the third drawing, an operation example of the apparatus shown in Fig. 1 is shown in a flowchart. In step S10, the examinee information is input by the examiner. In this case, for example, information such as the name, sex, date of birth, collection site (inspection site) of the examinee is input. In step S12, a confirmation screen I is displayed on the screen.

This example is shown in Figure 4. Among them, the confirmation screen I includes an inspection item regarding gender, an inspection item regarding the date of birth, and an inspection item regarding the collection site. Each item corresponds to an image (DD) for displaying a detailed description.

In the present embodiment, as shown in Fig. 5, the display state of the screen I can be confirmed in advance. For example, as shown in Fig. 5, the size of one of the inspection items is enlarged, and even if all of the inspection items are not read, only the enlarged portion is referred to, and the contents of the inspection items can be instinctively understood. Such customization can be performed freely by the examiner. For example, the size, color, gradation of the characters, and the like can be freely set or changed.

When the operation table 60 is pressed as shown in Fig. 5, for example, when the operation image 60 is pressed, the detailed description shown in Fig. 6 appears on the screen in a jump-out display. In this case, when the detailed description of the date of birth is displayed on the screen, the examiner is required to provide such information without referring to the instruction manual. Even if the knowledge is uncertain, it can be confirmed quickly. Step S14 in Fig. 3 reveals the steps showing the detailed explanation.

In step S16 of Fig. 3, all the inspection items of the displayed check list are constructed, and whether or not the input confirmed by the user is judged is performed. In the case where the confirmed input is performed for all items, the execution of the step of the next entity is allowed first. Incidentally, if there are some errors or problems, the process shown in Fig. 3 will end, and if necessary, the necessary steps will be re-executed before returning to the steps of the entity. In step S16, when all the items are judged to be the end of the confirmation input, the measurement step of step S18 is executed. That is, the X-ray beam is irradiated and scanned on the subject. Thereafter, the confirmation screen II is displayed in step S20.

Fig. 7 shows an example of the confirmation screen II. The checklist included therein includes a plurality of inspection items, for example, an inspection item including whether or not the object portion is placed in the analysis area, and an inspection item in which the measurement mode is correct. Even if this checklist is displayed, for example, as shown in Fig. 8, the examiner can customize it in advance. For example, in a specific sentence, color or emphasis display can also be performed.

In the third figure, in the case of the confirmation screen II displayed in step S20, some images are pressed, and a detailed description of the corresponding image is displayed in step S22. In step S24, it is determined whether or not the input confirmed by the user is performed for all the inspection items displayed on the confirmation screen II. In step S24, when it is determined that the input of the confirmation of all the inspection items is performed, the user sets the region of interest on the bone density image displayed on the screen in step S26. This setting is manually performed in the present embodiment, but it can also be automated. A confirmation screen III is displayed in step S28.

Fig. 9 shows an example of the confirmation screen III. The confirmation screen III after the customization process is displayed. By pressing and operating the image contained therein, detailed description can be made on the screen in step S30 of FIG.

In step S32 of Fig. 3, all the inspection items constituting the confirmation screen III are judged to be the end of the confirmation input, and the analysis processing is executed in step S34. This analysis process, for example, contains Selection of the bone part of the subject, calculation of the average bone density, and the like. In step S36, a confirmation screen IV is displayed.

Figure 10 shows this example. In the case where the image is pressed, for example, the image shown by symbol 62, a detailed explanation is displayed on the screen in step S38. This example is shown in Figure 11. Among them, the matter of calcification of the aorta was explained.

In the third diagram, step S40 determines whether or not all the inspection items included in the confirmation screen IV are confirmed to be input. When all the input is completed, the measurement result is displayed on the display screen in step S42. For example, the average bone density is shown as a measurement result. In step S44, it is determined whether or not the measurement result of the subject's subject is the first time, and this time, the first measurement is performed, and the confirmation screen V is displayed in step S46.

An example of this is shown in Fig. 12. Among them, the user determines whether the bone density value is normal (whether it corresponds to a decrease in bone mass), whether it is equivalent to osteoporosis, and inputs an input confirmation to the item. In Figure 12, if any of the three items confirms the input, the process ends. Incidentally, in the case where the image of the confirmation screen V is pressed in the same manner as described above, a detailed description of the corresponding image is displayed in step S48.

On the other hand, in step S44 of Fig. 3, the current measurement is judged to be the second or subsequent measurement, and in step S50, the confirmation screen VI is displayed.

An example of the confirmation screen VI is shown in Fig. 13. In the case where any image is pressed, in step S52, the detailed description of the corresponding image is displayed on the screen, and the input of the confirmation of any of the plurality of inspection items shown in FIG. 13 is performed. This process will end.

As described above, according to the above embodiment, after the step of each entity, the confirmation step is carried out, so that the result of the previous step of the entity step is used for the checklist, and the examiner confirms. According to this, some missing or wrong situations can be immediately identified by the examiner itself, because It is necessary to quickly perform the processing such as re-execution before the physical steps. Moreover, the contents of the checklist can be used to instantly identify each inspection item due to the customization of the examiner, and there is an advantage that it can prevent misidentification or different problems. For example, color processing allows users to emphasize more important projects or emphasize more important projects. Furthermore, in the above-described embodiment, in the display of the checklist, there is an advantage that the screen content can be simplified and the necessary information can be provided by using the two-stage display. In particular, the necessary items can be displayed in detail, so that the manpower time for taking out the instruction manual and referring to the manual can be saved.

In the above embodiment, since each examiner customizes each checklist, it is advantageous to obtain a display content that can be used to match the taste of the examiner. In the above embodiment, the bone salt amount measuring device is presented. However, the above configuration is naturally applicable to other medical devices. From the viewpoint of exposure of X-rays, it is preferable to apply the above configuration to a bone salt amount measuring device, and according to the above, it is possible to reduce the possibility that a series of steps must be performed again, so that a so-called lowering inspection can be obtained. The advantage of being exposed.
