R. Benton Pahlka, PhD, DABR

Senior Diagnostic Medical Physicist


School Education Degree Year
The University of Texas at Austin PhD Doctor of Philosophy 2010
University of Oklahoma HSC Masters Master of Science 2005
Texas A&M University Masters Master of Science 2002

Working together with our radiologists, technologists, and other experts, my philosophy is centered on patient safety by providing the best imaging possible at the lowest radiation dose consistent with the specific diagnostic task. I strive to develop imaging protocols that are tailored to the patient’s size and specific to the imaging task.

Clinical Interests:

Medical nuclear physics (PET/CT and SPECT/CT), fluoroscopy and CT radiation dose optimization, statistical data analysis

Research Interests:

Monte Carlo simulation, radiation dose optimization, artificial intelligence


Organization Name Role
American Association of Physicists in Medicine Member
American College of Radiology Member
