Automatic Reconstruction of Catheters in CT Based Bracytherapy Treatment Planning.

摘要

The aim of this study was to develop an automatic reconstruction of bracnhytherapy 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 nietallic catheters. Our algorithuls overcome a nuniber of difficulties which arrise when a large number of catheters are present. These include situations with intersecting catheters and with loop techniques.
