Outline of Final Research Achievements

We have developed a patient-specific collision detection simulator among a gantry, a couch, and a patient.This collision detection simulator has a capability to help oncologists/physicists to edit their treatment plans with ease and to make a decision of optimum irradiation direction when collision among them is detected. Furthermore, patient-eye-view function may be useful to give patients to new explanation about their treatments as informed consent.
