Abstract
The application belongs to the technical field of medical apparatus and specifically discloses a device for precision detection of a radiotherapy bed, which comprises a test block, a laser lamp set and an adjusting device. The test block is provided with a measuring surface with scale lines and through holes, the laser lamp set emits laser beams to the measuring surface, and the position deviation of the radiotherapy bed is determined according to the relative positions of the laser beams, the scale lines and the through holes. The device can realize quick and intuitive calibration and precision detection, and in addition, the device is integrated with a photoelectric sensor and a processing unit, so that automatic quantitative measurement and deviation compensation are realized.
