2023/05: Dr. Kevin Chung joins the lab

Dr. Kevin Chung joins our lab starting on May 1st, 2023. Dr. Chung received his Ph.D. in Medical Biophysics from the University of Western Ontario, Canada in early 2023. He developed methods and software for low-dose CT perfusion imaging and also has direct experience in PET kinetic modeling. Kevin will work on total-body PET kinetic modeling for FDG blood flow imaging and will be jointly supervised by Dr. Guobao Wang and Dr. Simon Cherry. Welcome Kevin!

2022/02: Siqi Li presented at SPIE Medical Imaging

Dr. Siqi Li presented his recent work on a deep kernel method for PET image reconstruction at the SPIE Medical Imaging 2022 held in San Diego. This is his first time presenting in person at an international conference in the pandemic, though he already presented three other talks virtually at IEEE-MIC 2021, SPIE Medical Imaging 2021, and Fully 3D 2021. Well done, Siqi!
