Abstract

The aim of this study was to develop an automatic reconstruction of brachytherapy catheters using CT data. Previously no such automatic facility has existed in any treatment planning software. To achieve this aim we have developed algorithms for the automatic reconstruction (which we term autoreconstruction) of plastic and metallic catheters. Our algorithms overcome a number of difficulties which arise when a large number of catheters are present. These include situations with intersecting catheters and with loop techniques.
