Title: "Intensity-based Registration of Prostate Brachytherapy Implants
and Ultrasound"

Abstract:

Prostate brachytherapy has emerged as one of the definitive treatment
options for early stage prostate cancer which entails permanent
implantation of radioactive seeds into the prostate to eradicate the
cancer with ionizing radiation.  Localization of these radioactive seeds
is necessary for evaluating the dosimetry. We address the seed
localization problem with introducing an intensity-based registration
framework between fluoroscopy and ultrasound. Since seeds are dominantly
visible in fluoroscopy and prostate anatomy is visible in ultrasound,
with this inter modality registration we can obtain the seeds positions
with respect to the surrounding soft tissues and hence perform the
dosimetry.
