Title:
COLLIMATOR FOR RADIATION THERAPY EQUIPMENT AND CONTROL METHOD THEREOF, AND RADIATION THERAPY EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2016/161923
Kind Code:
A1
Abstract:
A collimator (10) for a radiation therapy equipment. By disposing both a rear end position controller (5) and a front end position controller (6), a rear end position and a middle position of a single collimator leaf (1) can be calibrated simultaneously, and time and/or a motor revolution number for reaching the middle position from the rear end position of a certain collimator leaf (1) can be measured at any time. Since the distance between the rear end position and the middle position is constant and can be accurately measured, the certain collimator leaf (1) can be precisely calibrated and controlled to reach a precisely specified position. Since one-by-one calibration and control of the collimator leaves (1) can be conveniently achieved, transmission errors caused by a driving system of the different collimator leaves (1) and by unstable performance can be effectively overcome. Furthermore, a calibration can be performed before each time of field fitting, and then precise control can be achieved according to newly measured actual parameters.
