It has a structure for carrying it to the space between I102 and I102 and for carrying it into the cavity of the gantry 200. In addition, in order to move the subject up and down to a convenient height when performing diagnosis or surgery using the angio apparatus 100, and to set the body axis height of the subject to the rotation center axis of the cavity 201 of the gantry 200. In order to match, it has a structure that moves up and down as shown by arrow C in the figure. These operations are performed by operating various switches and buttons provided on the operation panel 22, but can also be performed by a command from the operation console 400.

Further, although the ceiling-mounted display unit 500 is used, in the embodiment, in view of cost and weight reduction, and space for pivoting which will be described later, a plurality (3 in the figure).
It is assumed that it is composed of a liquid crystal display device (table). It should be noted that, although the cost is somewhat high, for example, a plasma display may be adopted.

In the above system, the operation itself of the angio CT system is well known, and its explanation is omitted, and the ceiling-mounted display unit 500 which is a characteristic part of the present embodiment will be explained.

The ceiling-mounted display unit 50 in the embodiment.
Further details of 0 will be described with reference to FIGS.

FIG. 2 shows the structure on the ceiling side.

The guide rail 501 is provided with a connecting portion 501a at its essential portion, and the connecting portion 501a is fixed to the ceiling. By mounting the guide roller portion 502a of the base 502 on the guide rail 501, the base 502 can freely move with respect to the guide rail 501 in the arrow F direction in the figure (which is also the F direction in FIG. 1). .

Further, the guide rail 5 is provided on the base 502.
The slit 502b is provided in a direction orthogonal to the extending direction of 01. A slider unit 503 is mounted on the slit 502b so as to be movable in the direction of arrow I in the figure. As described above, a rod portion 504 having a braking function (a function of holding the position) in the vertical direction is rotatably fixed to the central portion of the slider portion, and a motor 514 is attached to the rotation shaft of the rod portion 504. Is provided. By driving this motor 514, the rod portion 50

A liquid crystal display device 507 is fixed to the liquid crystal display base member 510. Further, another liquid crystal display device 50 is provided at both ends of the liquid crystal display base member 510.
6, 508 are rotatably supported in the directions indicated by arrows J and K, respectively.
Is controlled by. Liquid crystal display device 5
The advantage of being able to change the orientation of 06 and 508 is that when there are multiple people in the same room system, the display screen can be seen from each position and it can be folded when not in use. This is because

The role of each motor is summarized as follows. First, by driving the motor 514, the orientation of the central liquid crystal display device 505 can be controlled. By driving the motors 515 and 516, the liquid crystal display device 5 of each of the liquid crystal display devices 506 and 508 on both sides is driven.
It will be possible to control the relative orientation with respect to 05.

The drive control of the motors 514 to 516 is performed by the drive signal from the control unit 517 shown in the embodiment. The control unit 517 includes a remote controller 52.
Receiving port 517 for receiving a signal from 0 (for example, infrared rays)
a is provided, and independently controls the motors 514 to 516 according to the signal received through the reception port 517a.

The remote controller 520 is provided with buttons for instructing the positive and negative directions of rotation for each of the motors 514 to 516. By operating these buttons, as a result, the individual motors are independently controlled. It will be.

FIG. 4 is a block diagram of the control unit 517 in the embodiment. In the figure, 1 is a CPU that controls the entire control unit, and 2 is a ROM that stores the operation processing procedure of the CPU 1. Reference numeral 3 is a RAM used as a work area of the CPU 1, and 4 is the reception port 51.
It is a receiver provided inside 7a. Motor drivers 5 to 6 supply drive signals to the motors 514 to 516.

The operation processing procedure is as shown in FIG. That is, it waits for receiving a signal from the remote controller 520 in step S1. When the reception is detected, the process proceeds to step S2, it is determined which motor the command is, and the process branches to any one of steps S3 to S5 according to the determination result. In either case, the corresponding motor is driven according to the commanded contents, and step S
Return to 1.

Therefore, for example, when the rotation button of the motor 514 is held down, the operation is repeated many times in the procedure of steps S1, S2 and S4, and as a result, continuous rotational movement becomes possible.

As described above, the ceiling-mounted display unit 500 in the embodiment adopts the liquid crystal display device, so that the weight can be remarkably reduced as compared with the case where the conventional CRT display device is adopted. You will be able to plan. Therefore, in the case of being composed of a plurality of CRT display devices up to now, it has been unavoidable to be fixedly installed in terms of weight and strength, but even if it is composed of a plurality of display devices as in the present embodiment, The ceiling-suspended display unit 500 can be transported with some force, and the vertical movement of the display unit 500 can be changed. Further, by adopting the liquid crystal display device, it is possible to add a mechanism having a simple structure for automatically adjusting each direction.

<Second Embodiment> The above embodiment is shown in FIG.
The position of the ceiling-mounted display unit 500 in the direction of arrow F and the height of the liquid crystal display device were manually set, and the orientation of each liquid crystal display device was set by the remote controller 520.

By the way, when using the angio apparatus,
In many cases, operations such as administration of a contrast agent and insertion into a patient's body such as a catheter are performed. Therefore, the doctor who performs this operation cannot operate the remote controller 520. This is because, when performing surgery, gloves for surgery are used and only medical instruments that have been sterilized and disinfected are touched. Therefore, a person who is not directly involved in the surgery operates the remote controller.

However, since it is the doctor who is operating that makes the image most visible, it is better that the doctor who is operating can directly instruct the direction of the display screen.

Therefore, it is desired that the ceiling-mounted display unit 500 can be operated by other means than manual operation.

One means for solving such a problem is voice operation. That is, the ceiling-mounted display unit 50
A voice recognition function is added to the control unit 517 of 0, the doctor recognizes a command issued by voice, and operates according to the result. Since the control target is at most three motors, it is only necessary to recognize the voice that specifies the liquid crystal display device to be controlled and its operation (rotation angle), and high recognition accuracy like ordinary conversation is not required. .

For example, an appropriate word is associated in advance with each motor, and then a word in the direction of rotation and a word indicating the degree thereof are associated in advance.

As an example, the motor 514 and the voice "center", the motor 515 and the "left", the motor 516 and the "right" are associated with each other in advance, and it is determined that the turning angle is to be uttered after that. Do not accept anything else.

As a result, for example, the doctor is the "center",
If you say "20 ° to the right", you will be able to rotate the motor 514 clockwise 20 °.

In this case, a microphone may be installed in place of the receiving unit 4 of the control unit 515, and voice recognition processing may be added immediately before step S2.

As a result of the above, according to the second embodiment, in addition to the first embodiment, there is an effect that a doctor during surgery can directly control the orientation of the ceiling-mounted display unit 500. Will be successful.

<Other Embodiments> In the above embodiment, the orientations (pans) of the three liquid crystal display devices were controlled. However, in the case of a liquid crystal display device, the weight can be remarkably reduced as compared with a CRT. The adjustment direction may be controlled not only for the pan angle but also for the tilt angle. In this case, it can be realized by adding a motor for tilt angle control.

Further, in the embodiment, an example in which three liquid crystal display devices are fixed has been described, but the present invention is not limited to this.

[0042]

As described above, according to the present invention, it is possible to provide a ceiling-mounted medical image display device which is not only lightweight but also excellent in operability, and an angio CT system using the same. .
