摘要：
FIELD: medicine.SUBSTANCE: invention refers to medical equipment, namely to patient's breathing control systems in radiation therapy complexes, and can be used for monitoring of patient's position in other clinical conditions. Disclosed is a method which includes using a computer to perform the following actions: primary capture and preprocessing of video streams, self-testing, data visualization, calibrating infrared sensors and creating a three-dimensional coordinate system with X, Y, Z axes, calculating a three-dimensional representation of clouds of the patient's depth points with X, Y, Z coordinates. Performing the patient's area of interest selection of the patient's surface, calculating the mass centres of the plurality of cloud points of the region of interest and reconstructing the surface, phase calculation and indication of the patient's chest surface amplitude of upper and lower limits, patient's body surface registration, integration with the control system. Complex data are used from at least two infrared depth sensors, processing of which increases accuracy of measurements, calibration of infrared depth sensors is carried out using an ArUco marker object, wherein calibration occurs once in a specified time period without patient presence, patient's chest surface motion amplitude is calculated along the vertical axis Z of the three-dimensional coordinate system formed using an ArUco marker object and having a vertical axis Z perpendicular to the horizontal plane of the patient's table, an X axis extending along the patient's table, an Y axis running perpendicular to the longitudinal axis of the patient's X-table, the center of the coordinate system is determined by the position of the ArUco marker object, data are obtained in the form of angles of rotation and displacements for positioning the patient as a result of using the recording process.EFFECT: invention provides higher accuracy of calculated respiratory phase and its interpolation indicating th
