Overview
My work focuses on PET imaging physics, including instrumentation, reconstruction, and image processing. We're working toward more quantitatively accurate PET, reduction in scan times and radiation dose in PET/CT, novel imaging devices for PET (and SPECT), and application of PET to more clinical and research needs. Positron Emission Tomography is now in widespread use as a clinical tool for oncology, neurology, and cardiology, and continues to be used as a research tool in these areas.

Performance comparison of a dedicated total breast PET system with a clinical whole-body PET system: a simulation study.
Journal Article Phys Med Biol · May 20, 2021 This paper presents a novel PET geometry for breast cancer imaging. The scanner consists of a 'stadium' (a rectangle with two semi-circles on opposite sides) shaped ring, along with anterior and posterior panels to provide high sensitivity and high spatial ...
