Abstract:Purpose
This study will investigate the feasibility of applying OSMS real-time surface guidance during radiotherapy for prostate cancer without body immobilization.
Methods
A retrospective analysis of data from 165 fractions of real-time surface-guided radiotherapy for five prostate cancer patients without body immobilization was conducted. Cone-beam computed tomography (CBCT) was used before radiotherapy to assess and correct the patients’ setup errors in 6 degrees of freedom (6-DOF). The OSMS gating system… Show more
