Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an X-ray CT apparatus having improved operability of an operation unit.

[0002]

2. Description of the Related Art In a conventional X-ray CT apparatus, an operation unit including a display, operation buttons, and the like is almost arranged on the surface of a scanner gantry unit.

[0003]

As described above, in the prior art, since the operation unit is disposed on the surface of the scanner gantry unit, there are the following problems.

That is, the operator always performs the tilt operation of the scanner gantry unit and the operation of the table at a position away from the subject. In particular, when performing a tilt operation or a forward / backward movement operation of the table to the opening of the scanner gantry unit, the operator takes care of the operation because the positions of the display and the operation buttons are far from the subject. In some cases, attention to the subject may be distracted, or blind spots may occur and safety confirmation may be insufficient.

When the scanner gantry unit is tilted, the operator must also move in the tilt direction. In particular, when the scanner gantry unit is tilted backward, the lower part of the scanner gantry unit protrudes toward the operator. There is a risk of contact with the operator. Even when operating the bed in the direction of the opening, the operator must look into the opening while operating the buttons, so that the operator always has to perform the operation and the safety check of the subject in an unrestricted posture.

Conventionally, the table side has a small space for arranging the operation unit, and it is difficult to arrange the display and the operation buttons because the subject gets in and out of the table. The actual situation was that no operation units were arranged.

An object of the present invention is to perform a reliable operation while confirming the safety of a subject, and to operate in a natural posture that does not easily cause fatigue while ensuring the safety of an operator, and a display device is also provided. It is an object of the present invention to provide an X-ray CT apparatus which can be recognized by the public.

[0008]

An object of the present invention is to provide an X-ray tube for irradiating an X-ray to a subject in an opening and an X-ray detector for detecting transmitted X-rays at desired tomographic positions of the subject at a plurality of angles. A scanner gantry unit having a housing in a housing, a subject table for moving the subject forward and backward with respect to the opening of the scanner gantry unit, and at least the scanner gantry unit and the subject table for operating the subject table. In an X-ray CT apparatus including an operation unit, the operation unit is constituted by a display operation unit and a button operation unit and is arranged adjacent to a predetermined position on the table.

The operation unit includes a display operation unit and a button operation unit. As a result, it is possible to arrange the table on a table with a small space. Further, in a preferred embodiment, the operation unit (display operation unit and button operation unit) which is divided into two parts is arranged adjacent to two predetermined positions on the side of the table in the vertical direction. Therefore, the object is not positioned wide on the same plane on the side of the table, and does not hinder the subject from getting on and off the table.

[0010] Since the operation unit is arranged on the table closest to the subject, it is possible to perform a reliable operation while confirming the safety of the subject. Can be operated in different postures,
The display can also be reliably recognized.
