Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention 1] The present invention relates to a patient monitoring system in a CT (computed tomography) apparatus.

[Technical background of the invention and its problems] Patient positioning in CT snowboarding is generally performed using a floodlight when setting the patient. When performing a scan, after copying the scanoscope image and planning the scan position, the CT machine mount is tilted (the mount is tilted back and forth), and the patient displayed on the monitor is When it is determined that the patient's position is incorrect based on image information such as a scanned image, the patient's position is often determined by moving the bed up and down.

In such a case, the operator of this apparatus in the operation room goes to the cradle or bed at the skill level and tilts the gantry and moves the bed up and down each time the patient is positioned.

However, it is extremely tedious for the operator in the operation room to enter the skill level every time the patient's positioning status is changed.

Therefore, a remote control system may be considered in which an operator can tilt the gantry and move the bed up and down from the control room.

However, when performing remote control, there is a problem in terms of patient safety compared to the case where the patient's safety is directly observed from the side of the patient and the gantry chill 1~ or the bed is moved up and down.

[Objective of the Invention] The present invention has been made in view of the above circumstances, and provides a zero-unit patient monitoring system that allows remote control of a pedestal and a bed under conditions of extremely high safety. The purpose is to
