Title:
OPTICAL STOP POSITION DETECTION APPARATUS AND MEDICAL ACCELERATOR TREATMENT HEAD
Document Type and Number:
WIPO Patent Application WO/2020/103437
Kind Code:
A1
Abstract:
An optical stop position detection apparatus and a medical accelerator treatment head, relating to the technical field of medical devices, capable of adapting to large-dose radiation, not prone to be damaged, and having high detection precision. The optical stop position detection apparatus is applied to detect position information of an optical stop (1) that makes arc-shaped motion, and comprises a connecting piece (2), a transformation mechanism (3), and a displacement sensor (4); the connecting piece (2) is fixed onto the optical stop (1); an input end of the transformation mechanism (3) is connected to the connecting piece (2); when the connecting piece (2) makes arc-shaped motion along with the optical stop (1), the transformation mechanism (3) transforms the arc-shaped motion of the connecting piece (2) into linear motion; the displacement sensor (4) is connected to an output end of the transformation mechanism (3), and is configured to detect displacement information of the linear motion at the output end of the transformation mechanism (3).
