- a tissue protector for use in the oral cavity is known. It is essentially a plastic part which, by means of its shape adapted to the patient, serves to displace the tongue, the lips and other tissue parts out of the ray path so that they emit the least possible dose of radiation
- WO 201 1/026662 A1 also discloses that, if appropriate, additional lead plates, which are advantageously exchangeable, could be attached to the tissue protector disclosed therein.
- Object of the present invention is an alternative way of
- the protective body at least one
- Protection body is thus chosen a different approach, as can not be irradiated tissue or organs before irradiation during radiotherapy can be protected. It is primarily no longer a question of a displacement of these tissue parts to be protected but rather of filling corresponding body cavities by means of the absorber body at the locations required for this radiation protection, so that this absorber body absorbs the radiation in the area in which the tissue not to be irradiated and / or not to be irradiated.
- the absorber bodies In order to be able to perform this protective function, the absorber bodies must have at least one curved, delimiting surface, since practically no straight surfaces exist in the human and animal body. Furthermore, the absorber body must have a density of at least 5 grams per cubic centimeter, preferably at least 10 grams per cubic centimeter. This density is therefore under normal conditions at 20 ° Celsius
