Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention emits X-rays from an X-ray tube to a subject on a table, detects the X-ray image transmitted through the subject with an imaging device, and generates a specific cross section. Regarding a control device that sets a series of operating conditions for an X-ray tomography device that takes tomographic images of The present invention relates to a control device for a line tomography apparatus.

[Conventional technology]

Generally, an X-ray tomography apparatus has an X-ray tube and an imaging device placed opposite to each other with a table on which a subject is placed in between, and the X-ray tube emits X-rays to the subject on the table. The X-ray image transmitted through the subject is detected by an imaging device, and a tomographic image of a specific cross section is photographed. At this time, the X-ray tube and the imaging device are connected and supported by a support, and a drive mechanism moves both the X-ray tube and the imaging device through the center point of the cut section (hereinafter referred to as the "cut section point"). They are moved in opposite directions relative to each other about a vertical line. The drive mechanism is then operated using controlled snow removal. In this state, when the operator operates the control device and moves the X-ray tube using the drive mechanism, the support body follows the movement of the X-ray tube due to the driving force, and the fulcrum part of the support body is rotated. By swinging around the center, the imaging device is moved in the opposite direction relative to the X-ray tube around a vertical line passing through the cross-section point, and the tomographic images of the object other than the desired specific cross-section are A tomographic image can be obtained by blurring and forming an image of the specific cross section on an imaging device without blurring it.

Here, the control device of the X-ray tomography apparatus includes operating devices for trajectory selection, vertical movement of the cut plane, selection of the cut plane pitch, irradiation field selection, horizontal movement of the table, vertical movement of the table, raising and lowering of the table, etc. There is a button switch, and a display section is also required to display the orbit time, cut section height, and film division display for irradiation field selection. Conventionally, these operating devices and display sections were It was a complex mix. When the operator performs tomography, the eighth
Using a conventional control device 10 as shown in the figure, the photographing position is adjusted by operating button 1 for vertical movement of the cutting plane, button 2 for table horizontal movement, button 3 for table vertical movement, and button 4 for table up/down movement. the trajectory, select the trajectory by operating button 5, select the cross section pitch by operating button 6, select the irradiation field by operating button 7, and operate the X-ray control unit (not shown). A series of operations were carried out to determine the X-ray tube voltage and tube current using the X-ray tube.

[Problem to be solved by the invention]

However, in such a conventional control device 10, as shown in FIG. 8, a large number of buttons 1, 2, 3, . Since the buttons are not arranged according to the flow of operations, the operator has to find and operate the corresponding button each time he/she sets each operating condition, which is not easy to operate and takes time. It was something. Also, during the series of operations, press buttons -3-14-? Sometimes I would press the wrong button or forget to press a certain button, and even if I started shooting, it would not proceed correctly under the desired conditions, and I would have to reset the operating conditions and try again. This was a waste of time for both the operator and the patient, and the testing efficiency was reduced.

On the other hand, in order to make the arrangement of the buttons 1, 2, 3, etc. described above and the display section 8 easier to understand, the control device 1
0 may be enlarged and arranged according to the flow of the series of operations described above, but generally this control device 10
There is a trend toward smaller size in order to reduce the footprint within hospitals. On the other hand, with regard to the types of tomography trajectories, the number of cross-section pitches, and the types of irradiation field selections, there is a tendency for these types to increase in order to improve the functions of the equipment. Buttons 1, 2, 3, etc. shown in
. . , and the display section 8 were even more complicated, making operation even more difficult. Furthermore, if the above functions are added to improve functionality, the number of buttons and display sections on the control device 10 will be increased, but what about this function? When accidents occurred after the equipment was delivered to hospitals, etc., it was impossible to deal with them.

Therefore, the present invention solves these problems and provides a control device for an X-ray tomography apparatus that is easy to operate, can be made compact, and can accommodate later addition of functions. The purpose is to

There is a ready button 18 that signals the start of the process.

Next, the operation of the control device 10' configured in this way will be explained with reference to FIG. FIG. 3 is an explanatory diagram showing an example of the flow of operations sequentially displayed on the display 13 of the control device IllO'. First, the control device 10' shown in FIG. 1 is powered on to begin setting a series of operating conditions for the X-ray tomography apparatus. ·At first,
In the first row (■) of Figure 3, select the imaging technique or positioning. At this time, as shown in FIG. 4, the input information display section 15 of the display 13 displays the items "R procedure" and "Positioning". If you want to select a surgical technique now, press the operating device l1 (indicated with an arrow) at the position corresponding to the input/information display section 15 where the item "r surgical technique" is displayed.

At this stage, the patient chooses between the imaging techniques, bucky imaging or tomography. At this time, as shown in FIG. 5, the input information display section 15 of the display 13 displays the items "buckie imaging" and "tomography". To select tomography now, press the operating device 11 (indicated with an arrow) at a position corresponding to the input information display section 15 on which the item "Tomography" is displayed.

Then, in the second stage (2), "tomography" is selected, and the process moves to the next third stage (2). At this stage, a straight trajectory, a circular trajectory, or a spiral trajectory is selected among the trajectory selections for imaging. At this time, as shown in FIG. 6, the input information display section 15 of the display 13 displays the items "straight line,""circle," and "swirl."Now, when selecting a straight trajectory, , the operating device 11 at the position corresponding to the input information display section 15 on which the item "straight line" is displayed (indicated with an arrow)
Press . Then, the "straight trajectory" is selected in the third stage (2), and the process moves to the next fourth stage (2).

At this stage, either the X direction or the Y direction of the linear trajectory is selected. For example, assuming that "Y direction" is selected, the process moves to the next fifth step (2) and r40'J is selected as the exposure angle. This means that the conditions for the tomography trajectory have been input.

Next, move on to the sixth stage ■. At this stage, it is selected whether to perform full-scale imaging or segmented imaging of the irradiation field. For example, if you select "Split shooting", move to the next step 7 (■), select "r2 split" as the number of divisions, then move to the next step 8 (■), and select whether the direction of the above two divisions is horizontal split. , select vertically or vertically. For example, if you select vertical division, this means that you have entered the conditions for the irradiation field.

Next, move on to the ninth stage ■. At this stage, one of 0, 1, and 2.3 is selected for the pitch of the cut section. if,
When the pitch of the cut section is neither 0.1 nor 2.3, the process moves to the next tenth stage 0, and one of 5, 10, 15, and 20 is selected. This means that the conditions regarding the pitch of the cut section have been input, and the input of the conditions regarding tomography is now complete. In this way, for example, -11
-1121? By sequentially selecting the desired items according to the information displayed on the input information display section 15 of the display 13, the user can automatically proceed to the next step and enter the required event.

Furthermore, other X-ray conditions (tube voltage, tube current, irradiation time, etc.). is input using an X-ray control unit not shown.

The operating conditions input in this way (information for controlling photographing/operation) are displayed on the output information display section 16 of the display l3 under the control of the display control means 12 shown in FIGS. 1 and 2. . That is, the operating conditions set as described above and sent from the control device 10' to the X-ray tomography apparatus (not shown) are displayed on the output information display section 16 such as surgical procedure, trajectory, and so on, as shown in FIG. Irradiation field, section pitch, xIilI

This can be confirmed on the display unit 16.

In this state, when the ready button 18 shown in FIG. 7 is pressed, the ready button 18 is pressed as shown in FIG.
A control command is sent from the control unit 17 to the X-ray tomography apparatus via the X-ray tomography apparatus, and the X-ray tomography apparatus performs preparatory operations according to the series of input operating conditions. , photography becomes possible. Thereby, the operator presses an imaging button (not shown) to perform X-ray exposure. In the operation flow shown in FIG. 3, for example, if the selection of the cutting section pitch of the ninth stage (3) and the tenth stage [phase] is to be omitted, the ready button 18 may be pressed at this point. In addition, if you wish to omit both the irradiation field selection in the sixth stage (■) and the selection of the cutting section pitch in the ninth stage O and the tenth stage [phase], press the ready button 1 when selecting the irradiation field in the sixth stage (■). Just press . In addition, in FIG. 1 and FIGS. 4 to 7, the display. The number of selection items displayed on the input information display section 15 of the ray 13 is set to four or less for one stage of the operation flow shown in FIG. Correspondingly, among the six operating devices 11, the first four become buttons for selecting items, and of the remaining two, one becomes a next button lln and the other one becomes a return button 11r. For example, when selecting the cutting section pitch and there are eight types of pitches, the next button lln is used to select the ninth pitch number because there are only four buttons for selecting items as described above. Stage ■
Although it is not among the four 0, 1, 2, and 3, the 10th stage [stock]
5.10 and 15.20, the next 10th stage [phase] item is displayed by pressing the next button lln. Also,
The return button llr is used to return to the previous stage and display the item by pressing the return button llr, for example, if the previous input is incorrect. For example, as shown in Figure 6, regarding trajectory selection,
When the operator wants to change to bookie shooting at the stage where "straight line", "r circle", and "swirl" are displayed, by pressing the return button llr, the previous step shown in Figure 5 is displayed. You can go back and display the ``bookie photography'' and ``tomography'' items.

〔Effect of the invention〕

Since the present invention is constructed as described above, the display l
The operating conditions of the X-ray tomography apparatus are input using a plurality of operating devices l1 provided at positions corresponding to the input information display section 15 of No. 3, and the display control means 12 displays information to be input using the operating device 11 and information that has already been input. The display 13 is controlled to display the conditions necessary for photographing based on the information obtained.
A display 13 having an input information display section 15 and an output information display section 16 sequentially displays information to be input using the operating device 11 on the input information display section 15, and information input using the operating device 11 to control the photographing operation. The information is displayed on the output information display section 16, and the control means 14 can control the imaging operation of the X-ray tomography apparatus using the operating conditions after completion of inputting the operating conditions using the operating device 11.

As a result, the input information display section l of the display l3
By selecting necessary items using the operating device 11 according to the items sequentially displayed in 5, a series of operating conditions for the X-ray tomography apparatus 115-16- can be set. Therefore, the operation is easier than in the past, input errors are reduced, and inspection efficiency can be improved. Furthermore, since each operating condition can be checked on the display l3 at the same time as it is set, it is possible to prevent photographing errors from occurring.

Further, the number of operating devices 11 for inputting operating conditions can be significantly reduced without being required for the number of items as in the conventional case, so it is possible to downsize the control device 10'. Furthermore, even if a function is added to improve functionality, it can be handled on the software using the control unit 17 of the control means 14 without changing the number of operating devices 11 or the display 13. Even if additional functions occur after the device is delivered to a hospital, etc., this can be fully accommodated.
