Immobilization as well as reproducibility of the affected part of the patient are the most important priorities during treatment and throughout the course of radiotherapy using a fractionated external beam. As to radiotherapy for the head and neck cancer, correct and precise trimming of the treatment portal is indicated, since the target volume is usually close to the neighboring organs at risk. Our newly developed immobilization method consists of a fixing device for the head and neck with a bite block and an individualized shell made of casting tape. By means of a semi-conductor detector which has also developed at our department, the magnitude and direction of patient mobilization are continuously monitored during the treatment. This newly developed device affords sufficient immobilization with correct and precise reproducibility. Concerning the further improvement of treatment technique this simple method is very useful for the daily treatment of patients with cancer of the head and neck region.
