CT-based software for 3-D localization and reconstruction in stepping source brachytherapy

Describes innovative software for catheter localization and 3D reconstruction in stepping-source brachytherapy applications. The patient information is a set of computed tomography (CT) slices, scanned during the implantation of brachytherapy catheters. Catheter geometry and patient anatomy are exported for use with dose calculation software modules. The errors produced by the system are also encouragingly low. Time savings were achieved compared with other traditional reconstruction techniques. Various automated procedures, 3D graphics and a user-friendly GUI have contributed to providing a powerful, comprehensive software tool that is directly useable in clinical practice.
