Enhanced Ultrasound Visualization of Bracytherapy Seeds by a Novel Magnetically Induced Motion Imaging Method

Abstract

We report our progress in developing Magnetically Induced Motion Imaging (MIMI) for unambiguous identification and localization brachytherapy seeds in ultrasound images. Coupled finite element and ultrasound imaging simulations have been performed to demonstrate that seeds are detectable with MIMI regardless of orientation to the imaging transducer and even when the seed itself is invisible in B-scans. in-vitro scans of a seed parallel and perpendicular to the transducer corroborate the simulation results.
