Event and scenario recognition in a video surveillance system for radiotherapy treatments
Résumé
Purpose/Objective: We propose a module to monitor a treatment room using video cameras in order to assist and reassure the radiation therapist and to record the sequence of events during the treatment delivery process. This module will complement other existing quality assurance systems by adding external information on the patient and the elements surrounding him or her (people and objects). Such information is today rarely taken into account and may be acquired by means of a global viewing scheme. This system may be used to help minimize errors such as patient's identity, detection of involuntary movements, positioning relatively to a unique referential, presence of treatment accessorizes (bolus, ..) and presence of staff or undesired elements during irradiation, etc.
