4. Evaluation of intrafractional motion for patients receiving whole brain radiotherapy in open-faced immobilisation masks
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Purpose/Background Patients receiving whole brain radiotherapy (WBRT) today are treated with an immobilisation mask which fully covers their face and therefore might be experienced as uncomfortable and claustrophobic. In recent years, optical surface scanning (OSS) systems have been implemented for patient positioning and real-time motion monitoring [1]. READ MORE
