ABSTRACT
PIPER (RTek Medical Systems, Pittsford, NY) is a commercial software system for preplanning, intraoperative planning, and postimplant dosimetry of permanent prostate brachytherapy. Its design goals were clearly aimed at real-time implant planning, guidance, and dosimetry, including:
• simple, work flow-oriented graphical user interface that can be run by operating room personnel;
• encapsulation of advanced technologies in image processing, feature recognition, and practical inverse planning.
