Design, Implementation, and Characterization of a Dedicated Breast Computed Mammotomography System for Enhanced Lesion Imaging

Abstract

The overall goal of this work is to design, implement, and characterize a novel dedicated mammotomography system for enhanced lesion detection. This novel system will allow fully 3-D imaging of a pendant, uncompressed breast using novel 3-D complex orbit capabilities. The system has been successfully implemented on a mounting system providing azimuthal and polar tilt capability. System components have been automated to allow synchronized tomographic data acquisitions at the touch of a button. Image corrections have been implemented to maximize image quality and initial phantom measurements are promising. Half cone-beam orbits have been implemented and investigated and have indicated they are feasible for a wide range of breast sizes. Future studies will focus on characterizing the system in terms of dose efficiency, contrast sensitivity, and evaluation for a range of breast sizes and compositions. Patient bed optimization will also be investigated.
