CT/MRI-based system for 3-D brachytherapy treatment planning

The paper presents a 3D brachytherapy treatment planning system based on CT/MRI images. Unlike other percutaneous radiotherapy planning systems, it provides doctors with an interactive source layout function, including accurate and quick dosage distribution calculation and dynamical 2D/3D display. A special template library and an integrated planning evaluation/alert subsystem are incorporated in the system. The system successfully realizes functions such as data acquisition, registration, segmentation, image processing, 3D reconstruction and planning report output. Various automated procedures, 3-D graphics and a user-friendly GUI enable the system to be a powerful one. Clinical practice has shown it well meets the therapeutic demands.
