We developed two new kinds of immobilization devices for the head and neck region, one for a treatment couch and the other for a simulator couch. These new devices are made of carbon resin and are composed of a head rest, shell(cast)mounting portion, and accessory mounting portion. The "simulator couch" type is convenient for treatment planning, CT, and MR examinations, and can be used as a treatment couch. The "treatment couch" type is used in the greatment room. A special exclusive interface is used as an attachment for the treatment couch. Three immobilization methods, i.e., bite, shell(cast), and a device for stereotactic radiotherapy are available. We examined the bending of the immobilization device with the arm-type interface. When 5 kg is loaded, the average amount of bending is 1.1 mm. This immobilization device is useful for small treatment fields in the head and neck region, multiple portal treatment, and fractionated stereotactic radiotherapy.
