A bed for loading an object;
  A gantry with a bed insertion opening,
  Contact detection means provided on the top, bottom, left and right of the insertion opening;
  Control means for controlling the operation of the gantry or bed according to the detection output of the contact detection means;
  An X-ray CT apparatus comprising: The X-ray CT apparatus according to claim 1, wherein the operation is any one of an operation for avoiding contact between the gantry and a bed, operation stop, and operation continuation. A bed for loading an object;
A gantry with a bed insertion opening,
A first manual switch for operating the gantry tilt drive;
A second manual switch for operating the bed forward / backward / up and down movement;
Touch sensors mounted on the top, bottom, left and right of the insertion opening;
First driving means for driving the inclination of the gantry according to the instruction of the first manual switch;
Second driving means for driving forward / backward movement and vertical movement of the bed according to an instruction of the second manual switch;
An X-ray measurement system including an X-ray source mounted on a gantry and an X-ray detector disposed opposite to the X-ray source;
Control means for capturing detection signals from the upper, lower, left and right touch sensors, a signal indicating the inclination of the gantry, and a signal indicating the position and height of the bed,
The control means includes
Gantry tilt control by the first driving means or vertical movement of the bed by the second driving means so that the touch state can be avoided when it is determined from the detection signals of the upper and lower touch sensors that the upper and lower touches are present. Alternatively, an X-ray CT apparatus having means for performing forward / backward control. A bed for loading an object;
A first manual switch for operating the gantry tilt drive;
A second manual switch for operating the bed forward / backward / up and down movement;
A gantry with a subject insertion opening on the bed,
Touch sensors mounted on the top, bottom, left and right of the insertion opening;
First driving means for driving the inclination of the gantry according to the instruction of the first manual switch;
Second driving means for driving forward / backward movement and vertical movement of the bed according to an instruction of the second manual switch;
An X-ray measurement system including an X-ray source mounted on a gantry and an X-ray detector disposed opposite to the X-ray source;
Control means for capturing detection signals from the upper, lower, left and right touch sensors, a signal indicating the inclination of the gantry, and a signal indicating the position and height of the bed,
When the control means determines that there is an up / down or left / right touch from the detection signals of the up / down touch sensors and the left / right touch sensors, the first control unit performs different avoidance operations for the up / down touch and the left / right touch. An X-ray CT apparatus having means for controlling the second driving means. A bed for loading an object;

First driving means for driving the inclination of the gantry according to the instruction of the first manual switch;
Second driving means for driving forward / backward movement and vertical movement of the bed according to an instruction of the second manual switch;
An X-ray measurement system including an X-ray source mounted on a gantry and an X-ray detector disposed opposite to the X-ray source;
Control means for capturing detection signals from the upper, lower, left and right touch sensors, a signal indicating the inclination of the gantry, and a signal indicating the position and height of the bed,
When the control means determines that there is an up / down or left / right touch from the detection signals of the up / down touch sensors and the left / right touch sensors, the first or second drive so as to avoid the touch if it is an up / down touch. An X-ray CT apparatus having means for controlling the means and controlling the interruption of measurement if measurement is in progress, and controlling the power interruption or measurement interruption if touching left and right. The control means, conditions and either X-ray CT apparatus according to claim 1 to 5, which was assumed to comprise a data table showing the relationship between the avoidance operation corresponding thereto including the detection signal of the touch sensor.
