Physical aspects of interstitial therapy using flexible iridium-192 wire.
A semi-automated procedure for the calculation of point doses and isodose distributions for a curved multi-wire implant is described. A dose optimisation method has been developed for producing acceptable dose distributions from non-ideal implants and the dosimetry of such implants is discussed. Source preparation, handling and stock control methods are described which facilitate the re-use of the encapsulated wire with consequent benefits in the reduction of staff radiation exposure and the costs of treatment.
