| Abstract: | In this paper, we propose a novel algorithm for detecting needles and their corresponding implanted radioactive seed locations in the prostate during Brachytherapy from trans-rectal ultrasound images. This is carried out efficiently using separable Gaussian filters in a probabilistic Gibbs random field framework. An approximation of the needle path through the prostate volume is obtained using a polynomial fit. The seeds are then detected and assigned to their corresponding needles by calculating local maxima. In our experiments, we were able to successfully localize over 85% of the implanted seeds. | ||
