Methods of radiotherapy are widely used in medicine. The Municipal Hospital Dresden operates in this field an X-ray therapy facility. With this, approximately 800 patients are treated each year, primarily in degenerative joint diseases, but also with near-surface tumors. To generate the radiation, an X-ray tube is used in such a system. With the help of special focus tubes of different size the size of the radiation field is adjusted to the clinical findings. A disadvantage of the system is that it does not recognize which tube is inserted. This means there is a risk of incorrect irradiation if the tube is selected incorrectly.
The aim of the project is to eliminate this source of error and to develop an automatic tube recognition, which reliably prevents a false irradiation through the use of the wrong tube and increases the safety for the patients. In order to facilitate the work of the medical personnel the tube recognition is to be carried out wirelessly without manual interaction over a Radio Frequency Identification (RFID) system. Commercially available RFID systems based on semiconductors are sensitive to X-radiation. For this reason, the innovative SAW IDENT Technology from SAW COMPONENTS Dresden is to be used, which will enable the wireless identification of the tubes even in continuous use under X-radiation.
The project is supported by the city of Dresden within the scope of the Special Funding Guidelines for Innovation Promotion.
