abstract = {PURPOSE
Brachytherapy (radioactive seed insertion) has emerged as one of the most effective treatment options for patients with prostate cancer, with the added benefit of a convenient outpatient procedure. The main limitation in contemporary brachytherapy is faulty seed placement, predominantly due to the presence of intra-operative edema (tissue expansion). Though currently not available, the capability to intra-operatively monitor the seed distribution, can make a significant improvement in cancer control. We present such a system here.
METHODS
Intra-operative measurement of edema in prostate brachytherapy requires localization of inserted radioactive seeds relative to the prostate. Seeds were reconstructed using a typical non-isocentric C-arm, and exported to a commercial brachytherapy treatment planning system. Technical obstacles for 3D reconstruction on a non-isocentric C-arm include pose …},

We defined general requirements for CAI software to be able to evaluate and enhance 3D Slicer for interventional applications in general, and not just for a specific system. 3D Slicer is found to be an appropriate basis for CAI software, as its built-in functions fulfill many requirements and missing functionalities can be conveniently added.
