title: [A new multi-channel LDR/MDR-afterloading-system (Inter-Pal-C38)].
abstract: The methods of temporary interstitial implantation of iridium-192 seed chains have been applied in Erlangen for two years in many cases of squamous cell carcinoma in the head and neck area, the cervix uteri or the anal duct. The afterloading procedure which at the beginning had to be performed manually involved partially considerable radiation-exposures of medical and nursing staff. Therefore we have developed a 38-canal machine for remote control afterloading with iridium-192 seed chains in LDR and MDR therapy which is working in a similar way as the already established methods of remote control afterloading in HDR therapy. Special technical features are the automatic afterloading procedure, the disconnecting of patient and machine for any length of time, the possibility to use the machine for several succeeding patients, and the modern computer control by an IBM PC with color monitor and alpha-numerical keyboard. The new machine is fast and easy to handle, protects the staff completely against radiation and, due to the possibility of disconnection and free mobility, makes it easier and more comfortable for the patient to stay within the radioprotection room.
