Title:
THERAPEUTIC DEVICE CONTROL SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2018/194297
Kind Code:
A1
Abstract:
Disclosed in one embodiment of the present invention is a therapeutic device control method for controlling a therapeutic device which emits radiation at a patient, comprising the steps of: acquiring, at regular time intervals, an input image signal, which includes information on a patient's posture and surrounding background and is composed of a plurality of pixels; digitally converting the input image signal so as to generate input image data including information on the contrast intensity of each of the plurality of pixels; analyzing whether the change in the input image data exceeds a preset change threshold value so as to generate reference image data; generating motion data, including a true pixel having motion and a false pixel not having motion, according to whether the difference between the most recently generated input image data and the reference image data exceeds a preset motion threshold value; and controlling radiation emittance of the therapeutic device according to whether the proportion of the true pixels in the plurality of pixels exceeds a preset control threshold value on the basis of the motion data.
