Abstract

A new approach for computing real-time dosimetry (RTD) for prostate brachytherapy is presented. Transrectal ultrasound (TRUS) and fluoroscopic images are fused to compute dosimetry. The frontal plane coordinates of the seeds are found in the fluoroscopic images and the remaining coordinate is computed from the TRUS. Our approach is verified on a phantom and tested on clinical data. A method for tracking intraoperative seed motion using TRUS is also presented.
