ABSTRACT:
Remote controlled afterloader apparatus and method positions high activity radioactive sources through a catheter within a human body for treatment of cancerous tissue. The afterloader includes an operating console and a remotely located computer controlled wire driver. The wire driver includes active and dummy source wires and channels for the storage of such wires. Stepper motors precisely position the wires in response to computer control and data from wire position encoders. An emergency DC motor retraction system provides a high degree of safety against system malfunction. Timing arrangements are included for timing patient treatment duration and emergency wire retraction time. A turret is provided with safety locking and cross-checking systems to permit use of multiple catheters. Treatment profiles are conducted from the maximum treatment position whereby only tension or retraction forces are used to position the active wire.
