Title:
CALIBRATION METHOD, CALIBRATION DEVICE AND CALIBRATION SYSTEM OF LASER POSITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/125662
Kind Code:
A1
Abstract:
The present application provides a calibration method, calibration device and calibration system of a laser positioning system. The calibration method comprises: arranging calibration devices in a first chamber and a second chamber, respectively, each calibration device comprising a calibration phantom, and the relative position between the calibration phantom of the first chamber and a preset center point of the first chamber being the same as the relative position between the calibration phantom of the second chamber and a preset center point of the second chamber; and comparing the position of a first positioning mark on the calibration phantom of the first chamber and the position of a second positioning mark on the calibration phantom of the second chamber. The technical solution provided by the present application can avoid the problem of deviation of an irradiation position to a patient from a correct treatment position due to inconsistency of a first laser positioning system of the first chamber and a second laser positioning system of the second chamber, and reduce or avoid unnecessary radiation dose to the patient.
