PhD thesis · cum laude
Development of Technologies for In-Room Image Guidance in Hadron Therapy
Six chapters on the design, calibration and clinical validation of an in-room imaging system for hadron therapy: from field-of-view extension in cone-beam geometry (nearly doubling the usable radius, from 102 to 181 mm) to breathing-correlated 4D imaging strategies, through to deep learning techniques for artefact reduction in CBCT.
