Topogram and 3DCT geometry calibration for image-guided proton therapy with in-room CT-on-rails

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 a robotic table to achieve sub-millimeter patient positioni...
