Abstract

Novel ultrasound image processing is enabling the development of a new set of tools that may lead to more consistent prostate brachytherapy planning, execution and quality assurance. We present progress of our effort in the area, including prostate elasticity modeling and segmentation, needle insertion planning and guidance using a robotic guide, and the localization of delivered radioactive sources. We will also present some of the techniques that we have developed for the measurement of the elastic properties of viscoelastic materials using longitudinal waves.
