Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of an X-ray CT panel display device.

[0002]

[Prior art]

 The X-ray CT irradiates the subject with X-rays, detects the X-rays that have passed through the subject, and performs this over 360 ° to reconstruct an image and generate a tomographic image for diagnostic purposes. It is a device used for

When the subject is imaged by using the X-ray CT to obtain an image, an operation console is used to give various imaging conditions and instruct the start and end of the imaging. Recently, a touch panel type has been used as the operation console format, and it is easy to operate and the technique (shooting condition) currently set can be clearly indicated by lighting. From now on, its usefulness has been recognized.

As an imaging method by X-ray CT, there is a method called multi-scan, in which a plurality of scans for a plurality of slice planes is performed for one subject. In this multi-scan plan, different technics are often set for each acquisition, but the panel does not show the full list of different techniques, and the current technique is It is only displayed. Also, when one acquisition (AQ) technique was changed, it was not known how the other AQ techniques would change.

FIG. 7 shows an example of a touch panel type display screen that has been conventionally used. In the figure, reference numeral 1 is a panel display screen for displaying the current operating conditions and operating as an input switch by touching. Reference numeral 2 is a scan condition change key, and the scan condition is currently set or changed, and "end of change" is displayed. When the scan condition change key 2 is pressed, a "scan condition change" display appears, and a screen for setting and changing the scan condition is displayed. When this key is pressed after setting and changing the scan conditions, "end of change" is displayed as shown in FIG. 7, and the imaging technique set as shown in the figure is displayed on the panel display screen 1.

Reference numeral 3 is a scan time display key, and 4 is a tube current display key for displaying the tube current of the X-ray tube. By pressing this key, the tube current value can be changed. The X-ray dose can be adjusted by changing the tube current value.

Reference numeral 5 is a slice thickness display key showing a set value of the slice thickness of the tomographic image. Among the display keys shown in the figure, the ones with diagonal lines indicate that they are lit, and that they are operating under the conditions of this display.

[0008]

[Problems to be solved by the device]

 By the way, in the conventional panel display screen 1 shown in FIG. 7, the tube current display key 4 displays 80 mA, and when the X-ray CT is switched on and operated, the first AQ current setting is performed. I know that the value is 80mA, but I didn't know if the technique settings were different from the second time onward.

Further, when the technique is changed, it is not known whether this change will affect the setting of other AQs. Therefore, there is concern about changing the setting on the panel display screen 1. Therefore, the setting could not be changed substantially.

As a method for solving this, all the technics in each slice after the second time may be displayed on the display screen, but it is impossible because the screen area is limited.

The present invention has been made in view of the above points, and an object thereof is to identify whether or not different techniques are set without complicating the technique display on the panel display screen. It is to realize an X-ray CT panel display device capable of displaying possible images.

[0012]

[Means for Solving the Problems]

 The present invention, which solves the above-mentioned problems, is provided with an input means for inputting data for changing setting values of shooting condition data, a shooting plan database storing data of shooting conditions input based on a shooting plan, and a shooting condition database. Shooting condition changing means for rewriting the data stored in the shooting plan database by setting value change input, and shooting condition display setting means for reading the data stored in the shooting plan database and setting a flag of the corresponding data And a display control means for generating and outputting underline data attached to the corresponding display key based on the flag set by the photographing condition display setting means, and an input means for displaying the condition and changing the display condition. And a display unit composed of a touch panel used as the above.

[0013]

[Action]

 When the data for changing the photographing conditions is inputted by the input means, the photographing condition changing means rewrites the photographing conditions stored in the photographing plan database. The photographing condition display setting means reads the data of each AQ from the photographing plan database, sets the photographing condition data, and then sets a flag at the position where the data exists. The display control means creates data for underlining the display portion indicating the flagged shooting condition data, and the display means displays the underline on the corresponding display portion.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram of an apparatus according to an embodiment of the present invention. In the figure, reference numeral 11 is an input device composed of each key of the touch panel, and when the current tube current setting is 40 mA, when the user wants to change to 60 mA, the 60 mA key becomes the input device at that time.

Reference numeral 12 denotes an input reception device that determines whether or not an interrupt signal such as a shooting condition change command is input from the input device 11 and determines the processing of the reception result when the interrupt signal is received. is there.

Reference numeral 13 denotes an imaging plan database in which the imaging conditions planned in advance are stored as shown in FIG. Other imaging conditions such as tube voltage, slice thickness, slice interval, scan time, etc. are entered in the imaging plan database 13, but they are omitted.

Reference numeral 14 denotes a photographing condition changing device which receives a photographing condition changing command input from the input receiving device 12 and rewrites the data stored in the photographing plan database 13. When the shooting is performed with a tube current of 60 mA, if 80 mA of the tube current display key 4 is pressed, the tube current values in the shooting plan database of FIG. 2 are all overwritten by one step. That is, 60 mA → 80 mA, 80 mA → 100 mA, 100 mA → 130 mA.

When inputting a change command for changing the panel display screen 1 to another mode screen by pressing the scan condition change key 2 in the input device 11, the data of the change screen is displayed on the display control device 16. It is a screen display changing device for outputting.

Reference numeral 17 reads out the shooting conditions such as the tube current from the shooting plan database 13 for each AQ, outputs them to the display control device 16, lights the respective display keys on the panel display screen 1, and stores them in the shooting plan database 13. It is a photographing condition display setting device that reads out the stored tube current values of all AQs, sets a flag for underlining the corresponding tube current display key 4, and outputs the flag to the display control device 16.

Reference numeral 18 denotes a display device that displays data input from the display control device 16, and displays various touch panel screens in addition to the panel display screen 1. Next, the operation of the embodiment configured as described above will be described using the flowchart of FIG. 3 and with reference to the panel display screen 1 of FIG. In the apparatus of this embodiment, the shooting plan data is stored in advance in the shooting plan database 13 in another mode, and the display is performed based on this data.

In FIG. 3, (a) is a flowchart of the operation of the present embodiment, (b) is a diagram in which the data stored in the shooting plan database 13 used for explaining the operation is encoded, and (c) is It is the figure which showed the structure of the flag for mA range display, and has shown the position of six tube current values which set a flag. For example, if a tube current value of 80 mA is stored in the shooting plan database 13, flag 1 is set at the position of "3", and if there is no 40 mA, there is no flag at the position of "1" and it becomes 0. Is.

After the X-ray CT is switched on and data is stored in the imaging plan database 13 in another mode as shown in FIG. 2, the operation of the panel display device of this embodiment is started based on this data. . The same operation is performed when the photographing technique is changed by the input device 11.

Step 1 The tube current display key 4 on the panel display screen 1 displays the tube current mA (1) of AQ1 in the imaging plan database 13 shown in FIG. In the example of FIG. 7, 80 mA lights up.

Step 2 Clear the flag []. This is not the case if the flag that was set before remains, so delete it.

Step 3 The AQ number of the shooting plan database 13 is set to i and i = 0. The AQ number is 1 to n.

Step 4 Let i = i + 1. That is, it starts from AQ number 1. Step 5 The imaging condition display setting device 17 reads the tube current value corresponding to the AQ number from the imaging plan database 13 and sets the flag [mA (i)]. That is, if mA (i) is 80 mA, 1 is set in the Bragg 3.

Step 6 Check if i ≧ n. If not, return to step 4. If so, the reading of all of AQ1 to AQn and the setting of the flags have been completed, so the routine proceeds to step 7.

Step 7 Since the setting of the flag is finished, the procedure proceeds to the next step, and the procedure of underlining the tube current display key 4 of the tube current value at which the flag is set is executed. Let mA be j and j = 0. j is a number from 1 to 6.

Step 8 Let j = j + 1. That is, it starts from 40 mA of mA number 1. Step 9 Check if the flag [j] in the photographing condition display setting device 17 is set. That is, it is checked whether the flag is set. If not standing, go to step 11. If standing, proceed to step 10.

Step 10 The display control device 16 looks at the flag in the photographing condition display setting device 17, and if the flag is set, the display key corresponding to the flag of the tube current display key 4 on the panel display screen 1 is displayed. Data for drawing an underline at the bottom is created, and the corresponding display key of the display device 18 (in this case, the panel display screen 1) is underlined.

Step 11 Check if j ≧ 6. Otherwise, return to step 8. If j ≧ 6, all tube current values have been checked, and the process ends.

FIG. 4 shows the panel display screen 1 obtained by the above procedure. That is, the data of the photographing condition database 13 of FIG. 2 is displayed on the tube current display key 10 of FIG. 4 and the screen is underlined at 60 mA, 80 mA and 100 mA.

When the 100 mA key of the input device 11 (in this case, the tube current display key 10) is pressed while 80 mA in FIG. 4 is lit, the input reception device 12 performs interrupt processing and causes the imaging condition changing device 14 to operate. Input a signal to the effect of 100mA. Imaging condition change The device 14 rewrites the data of the imaging change plan database 13 from the data of FIG. 2 to the data of FIG.

Based on the data of the photographing plan database 13, the photographing condition display setting device 17 reads the tube current of each AQ from the photographing plan database 13 and sets a flag according to the procedure of FIG. Draw on the display key of the tube current value with a flag. Underline data is input to the display device 18, and the display of the tube current display key 10 on the panel display screen 1 shown in FIG. change.

As described above, according to the present embodiment, in multi-scan, it becomes clear whether or not the set value of the tube current is other than the currently displayed value, and the setting of a certain technic is changed. If you do, you can see at a glance how the change has changed the range of the minimum and maximum values of the technique already set.

The present invention is not limited to the above embodiment. In the embodiment, the example in which all the set values are increased by one step when the displayed tube current value is increased by one step is shown, but the change can be made only for the changed tube current value. It can also be configured with software instead of hardware.
