    Current Research and Scholarly InterestsI am mainly working on designing high-speed and low-noise/jitter instrumentation, and data acquisition electronics for building a 16-module TOF-PET system to achieve ~100 ps CTR and 50 cm FOV. This means a > 2-fold signal-to-noise-ratio (SNR) improvement relative to the best commercially-available PET scanner; ∼214-250 ps CTR Siemens Biograph.
    This highly compact TOF-PET system will be integrated to a CT scanner for acquiring both functional and structural information in clinical imaging
