装置。 X-ray CT with tilting gantry and patient table with move-to-scan function
In the apparatus, an external positioning light is provided in the gantry and provides a bright line at a position a certain length away from the center of the slice plane of the gantry with a tilt mechanism in a certain direction, and means for reading the tilt angle of the gantry. an up/down drive device that can move the table up and down and detect its height; an in/out drive device that can move the table in the scan axis direction and detect the amount of movement; A switch for commanding the tow scan function, and reads the output signal of the switch, tilt angle, table height, and table movement in the scan axis direction, and operates the up/down drive device and the in/out drive device as appropriate. The table is driven according to the tilt angle of the gantry, and the patient position, which has been aligned by an external positioning light, can be automatically sent to the inferior plane of the slice. A patient table positioning device with tilt correction for an X-ray CT apparatus, characterized in that it is configured as follows.
