Development of Technologies for In-Room Image Guidance in Hadron Therapy

Politecnico di Milano · November 2019 - March 2024 · Supervisor: Prof. Guido Baroni

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 to breathing-correlated 4D imaging strategies, through to deep learning techniques for artefact reduction in CBCT.
