Dianna D. Cody, PhD, FAAPM, DABR

Professor, Chief of Radiologic Physics Section, and Director of Clinical Operations; Department of Imaging Physics, Division of Diagnostic Imaging MD Anderson Cancer Center

Dr. Cody trained as a bioengineer at the University of Michigan (MS and PhD) and attained American Board of Radiology certification in Diagnostic Medical Physics while on staff at Henry Ford Hospital in Detroit, Michigan. She spent 13 years at Henry Ford, and in 2000 she joined The University of Texas M.D. Anderson Cancer Center in Houston, Texas. She is currently the Imaging Physics Department Clinical Director, and the Chief of the Radiologic Physics Section (CT, rad/fluoro, mammo, interventional, PACS). She also leads a team of CT physicists who support 16 clinical scanners, 4 research scanners, and 12 hybrid scanners. She is involved in small animal CT imaging research, CT medical physics graduate and technologist education, and CT related workshops for practicing medical physicists.
