When this switch S3 is pressed, data formats such as the patient's name, gender, age, etc. are displayed on the CRT 5 of the operator console, and the data can be entered manually from the keyboard.

As described above, the operator of the X@CT apparatus successively selects the switches on the panel surface of the operator console, but the conventional switch method as described above has the following drawbacks.

(1) Operation is difficult unless the operator (engineer or doctor) memorizes the order of the switches to be selected (4). On the other hand, in hospitals, there are times when it is desired to perform a diagnosis using the X1ilCT apparatus at the end of an emergency even late at night when a full-time operator is not available. However, in such a case, X1IiiiC
There was a problem in that doctors who were not familiar with the T device were unable to perform imaging.

[Object of the present invention]

The present invention solves the above-mentioned drawbacks, and provides an X-ray CT apparatus that has an operator console on which switch operation procedures are displayed in an easy-to-understand manner, and that even an operator who is unfamiliar with the apparatus can easily operate the apparatus. With the goal.

[Summary of non-invention]

The invention is to provide each switch with a light-emitting means that can call attention to a specific switch, and as the operation procedure progresses,
This is an X-ray CT apparatus in which the light emitting means instructs which switch is to be selected next.

[Explanation based on examples]

One embodiment of the present invention will be described in detail based on the drawings.

FIG. 2 is a diagram showing an example of a panel surface of an operator console used in the X-ray CT apparatus according to the present invention. In FIG. 2, 5 is a CRT, which is mainly used to display tomographic images of a subject (patient). 6 is a group of switches on the keyboard, and these keys (for example, keys representing alphabets and numbers) are used to input the patient's name, gender, age, etc. into the computer. Reference numeral 7 denotes a panel section on which various operation switches are provided, which is a key point in the invention. This panel part 7
As shown in FIG. 2, a large number of switches S□, S2゜, . . . are provided. These switches are usually push-button type switches, and a light-emitting device is provided inside the push-button cap. Some specific examples of this light emitting means include light emitting diodes, lamps, and plasma elements. Of course, by having this light emitting means illuminated within the pushbutton cap, it is possible to direct the operator's attention to the particular illuminated switch.

The light emitting means is not limited to the above, but for example, the light emitting means may be the switch S1. S2. It is possible to pull it even if it is placed outside the cap of , , and directly near the cap.

In addition, switch 311821-0. Although push-button switches are superior in terms of operability, the present invention can be applied to switches based on other principles.

The operation of the X-ray CT apparatus having the operator console of FIG. 2 constructed as described above is as follows. In addition,
FIG. 3 is a diagram for explaining various switch operations of the operator console, and the operations will be explained with reference to FIG. In Figure 3, each switch is divided into three columns. The leftmost column shows the type of switch pressed by the operator, and the middle column shows the light emitting means provided for each switch that lights up in dimming light. The rightmost column represents
The figure shows that all the light emitting means provided in each switch are lit. Furthermore, the word 2 written in the square representing a switch represents the name of that switch.

) First, turn on the power switch S□ in FIG. This is shown in the first row of the leftmost column of FIG.

(c) After turning on the power switch s1, it is necessary to turn on the warm-up switch S2 in order to warm up each component of the X-ray CT apparatus. In the conventional operator console, the operator had to memorize the procedure, but in the uninvented system, after turning on the power switch s1, the warm-up switch s2 is automatically turned on.
The light emitting means provided in the lamp operates to dim the light.

Therefore, the operator can proceed to the next stage of operation by turning on the switch that is lit in dim light next time. The dimming and dimming of the warm-up switch S is shown in the middle column of FIG.

(U) On the other hand, the rightmost column in Figure 3 shows the switches that are currently in operation.In the example in Figure 2, all the switches that are in operation are lit (lit at a constant brightness without blinking). The operator is informed of this. In FIG. 3, the light emitting means operated by the power switch continues to light up as long as the X-ray CT apparatus is driven (unless the power is turned off).

(g) The operator turns on the warm-up switch S2, which is dimmed.

(g) In response to this switch S2 being turned on, the X11CT device enters a warm-up state, and the warm-up switch S2 is fully lit to notify the operator that it is currently warming up. This is shown in the second row of the rightmost column in FIG.

(E) Once this warm-up is completed, the patient to be examined must be placed on the ped 4 shown in FIG. 1 (A) and the patient switch S3 must be turned on. When warm-up is complete, the 211 patient switch S3 automatically flashes to inform the operator of the next switch to select.

Hereinafter, in the same manner as described above, in the X-ray CT apparatus of the present invention, the switch to be selected next is automatically turned on or off at each operation step to notify the operator. Therefore, the operator must first switch the power switch S of the X-ray CT device.
1, the X-ray CT apparatus can be operated by simply turning on the blinking switches one after another.

Note that there may be cases where a plurality of switches blink at the same time. For example, do you scan from the head to the feet (switch name: Head First)?
Or vice versa, from the feet to the head (switch name F)
This is a case in which the operator is asked to make a judgment regarding ``eet First''. In this case, it is sufficient to select one of the plurality of blinking switches. Since words representing the function of each switch are concisely displayed on the cap of each switch, the operator can easily make the above-mentioned judgment.

Note that it is clear that the above-mentioned blinking display of each switch can be easily achieved by using a converter.

In the above explanation, it was explained that the light blinks to draw the operator's attention to a specific switch, but this is not limited to this. For example, instead of blinking, you can change the brightness of the light to other switches. It is also possible to perform lighting with a brightness different from t 11 ). Furthermore, lighting with a special color may be performed.

〔Effect of the invention〕

As described above, according to the present invention, since the operator is automatically instructed which switch to select next,
Even operators who are unfamiliar with T equipment can easily perform X-ray CT
Able to operate the device. Further, by operating in this manner, the occurrence of operational errors can be reduced.
