Title:
FIELD VERIFICATION DEVICE AND RADIOTHERAPY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/073540
Kind Code:
A1
Abstract:
Disclosed are a field verification device and a radiotherapy system, relating to the field of radiotherapy. Two calibration lines are provided on a first surface of a main body of the field verification device, and a second surface is provided with a verification component comprising verification metal wires, wherein the two calibration lines can align the field verification device with the isocenter of a radiotherapy device, so as to ensure that the imaging of the verification component on an imaging component can indicate a desired field. Verification personnel can directly verify whether the position of the field of a beam is accurate according to the deviation between the imaging of an actual field on the imaging component and the imaging of the verification component obtained by comparison. The accuracy is high when field verification is performed by using the field verification device.
