System for remote positioning of a radioactive source into a patient including means for protection against improper patient exposure to radiation

摘要: Remote controlled afterloader apparatus and method positions high activity radioactive sources through a catheter within human body for treatment of cancerous tissue. The including an operating console remotely located wire driver. driver includes active dummy source wires channels the storage such wires. Stepper motors precisely position in response to computer control data from encoders. An emergency dc motor retraction system is provided wire. A non-computerized cross-check interlock provides degree safety against malfunction. turret with locking cross-checking systems permit use multiple catheters. inserted into each verify integrity prior insertion Treatment profiles are conducted maximum extension whereby only tension or forces used
