CASS Brachytherapy System

The CASS Brachytherapy System is a highly advanced 3-D Graphic and Imaging System. It combines actual CT or MR images with graphic renditions of tumor volumes and radioisotope seeds, catheters, and calculated dosimetry zones for full 3-D dose volume optimization. A graphic rendition of tumor volumes can be projected in 3-D stereotactic frame space with angiographic localizers for confirmation of radioisotope seed positions and dosimetry. The system also provides multiple windowing image slice viewing with isodose contours.
