Abstract

A 3D surface image capturing system is used to obtain data defining the external anatomy of a patient for application in radiotherapy treatment and planning. The system is first calibrated to the isocentre of the planning or treatment room. The system is used to assist in patient identification, patient positioning and during both treatment planning and the treatment itself, to ensure that the treatment is as localised as possible to the tumour under treatment, taking account of patient movements including respiration, both during a course of treatment and between courses of treatment. Since the system is a surface imaging system, the use of conventional marker systems for tracking patient movement can be avoided.
