Radiation treatments have been attracted many interests as one of revolutionary cancer therapies. Today, it is possible to treat cancers without any surgical operations. In the fields of the radiation treatments, it is important to regist the 3D position of the cancer inside the body precisely and instantaneously. To achieve 3D position registrations, we aim at developing a compact camera for 3D measurements. In this trial, we have developed a high-speed pattern projector based on the spatiotemporal conversion technique. In experiments, we show some experimental results for the 3D registrations.
