Quantitative Breast Lesion Imaging and Characterization Using a Combined X-Ray CT-Gamma Camera Methodology

Abstract

The purpose of this research is to develop tools and techniques for the measurement of radionuclide uptake in breast lesions using a combined x-ray CT-scintillation camera imaging system. The developed techniques are also potentially useful for other types of cancers, as well as for other diseases. Major projects in the second funding year include: (1) development of a scatter estimation method that can estimate the amount of detected scatter in arbitrary energy windows and for arbitrary radionuclide photon emission energies, (2) implementation of this scatter model into iterative reconstruction algorithms, and (3) testing of these new scatter estimation and reconstruction methods using Monte Carlo simulations and experimental measurements.
