Here at the RDI group, we take a systematic approach to develop advanced radiological imaging techniques that help to tackle some of the most challenging diseases that we are facing today, such as brain cancer, cardiac diseases, and neurodegenerative diseases. Our efforts are focused in exploring various technological forefronts to develop radiation sensors that can detect incident particles with better efficiency, spatial, energy and timing accuracy.
1) We develop and apply ultrahigh performance gamma ray imaging sensors for demanding SPECT and PET applications.
2) We study advanced image formation techniques, such as artificial compound eye gamma cameras and adaptive aperture design, to improve the tradeoffs between spatial resolution and sensitivity.
3) We develop statistical techniques, such as the modified uniform Cramer-Rao bounds (M-UCRB), for designing and optimizing complex radiological imaging systems that could offer optimum efficiency for attaining useful imaging information and
4) We explore imaging techniques that utilize a broad range of EM radiations (from radio-frequency, visible photos, soft x-rays to energetic gamma rays), and multiple physical and chemical principles to produce tomographic images for visualizing physiological processes inside biological samples, living animals and patients.
