Title: Zekun Li and Low-Count Quantitative SPECT Imaging
Introduction
Zekun Li is an inventor based in St. Louis, Missouri, and is associated with Washington University. His work includes an invention for low-count quantitative single-photon emission computed tomography (SPECT) imaging.
Latest Patents
Li is credited with 1 patent, titled “Systems and Methods for Low-Count Quantitative Projection Domain SPECT Imaging.” The invention describes a system for low-count quantitative SPECT imaging that stores a subject’s CT scan and defines volumes of interest (VOIs). It models the probability that photons emitted from those volumes will be detected in different projection bins, adjusts the model to account for stray-radiation noise, and uses detected photons from an alpha-particle-emitting isotope to identify their source VOI.
Career Highlights
The patent reflects work at the intersection of medical imaging, computational modeling, and radiation detection. Its approach uses CT-based anatomical information and a noise-adjusted system model to support quantitative imaging when photon counts are low.
Collaborations
Li’s listed coworkers include Abhinav Kumar Jha and Daniel Thorek. The patent’s technical focus connects their work to research in SPECT imaging and quantitative analysis.
Conclusion
Zekun Li’s patent presents a computational approach to low-count SPECT imaging that combines CT-defined volumes, radiation-noise adjustment, and detected-photon data to determine the likely source of emissions.
