Introduction: To evaluate the feasibility of Monte Carlo (MC)-based patient-specific quality assurance (PSQA) for MR-guided online adaptive radiotherapy and to explore the potential to eliminate the post-delivery measurem...
Topogram and 3DCT geometry calibration for image-guided proton therapy with in-room CT-on-rails [0.03%]
基于室内心电图引导的质子治疗的层厚校准与几何标定研究
Giovanni Fattori,Riccardo Via,Antony J Lomax et al.
Giovanni Fattori et al.
In-room computer tomography (CT) on-rails scanners are available in proton therapy centers but often limited to control imaging, due to geometric distortion and lack of integration. We present a calibration method combining CT-on-rails with...
