The aim of this study is to develop an automatic reconstruction of brachytherapy catheters using CT ͑computed tomography͒ data. Previously no such automatic facility has existed in any treatment planning software. To achieve this facility we have developed tools for the automatic reconstruction ͑which we term autoreconstruction͒ of plastic and metallic catheters. These algorithms overcome a number of difficulties which arise when a large number of catheters are present. These include situations
