[Clip markings of the uterus and the urinary bladder for the dosimetry of intracavity and percutaneous radiotherapy (author's transl)].
The exact marking of certain regional landmarks of the anatomy permits the determination of the co-ordinates of these points by stereoscopic diagnostic radiology. The mid-point of the upper margin of the symphysis is selected as the origin of the co-ordinates. The markings of the uterus are placed through the laparoscope with silver clips. The markings in the urinary bladder are placed close to the ureteral orifices through the cytoscope. The doses of radiation generated by the sources of radiation (tubes, colpostat, vaginal cylinder, cervical plate) can with this new marking technique not only be measured experimentally in anatomically well-defined points in the body but the dosage (the energy) can be calculated by the computer. In as many points in the body as desired. The maximal permissable dosage in the tumor can be determined with special consideration for the avoidance of radiation lesions to marked adjacent points such as the ureteral orifices.
