Technical Field
The field relates to the field of medical instruments, in particular to a radiotherapy positioning body frame plate.
Background
Radiotherapy is one of the indispensable main methods for curing malignant tumors, and localization is the first link of radiotherapy. The result of the patient's CT positioning scan is used as the basis for the target delineation and the establishment of the coordinate system of the patient's body. The doctor delineates the patient with skin markers during CT scout scans and uses the skin markers as location reference points during radiotherapy.
Currently, in the positioning CT scan and radiotherapy, a positioning frame plate is usually used to position and fix the patient. For the error direction of radiotherapy, there are errors of head and foot direction, left and right direction, up and down direction and deflection direction. Errors for the first three dimensions are easier to detect by measuring skin markers and thus correct. The deflection error is the deflection of the body, and because the skin and the skeleton have certain looseness, the body is deflected but the skin mark deflection is not obvious, so the deflection error is not easy to be found and corrected, and the irradiation accuracy and the radiotherapy prognosis effect are influenced.
