J. Anthony Seibert

Clinical Interests

Dr. Seibert's clinical interests are directly related to radiological imaging. He specializes in radiation dose metrics for ionizing radiation examinations for monitoring, tracking and reporting of patient encounters and radiation doses, and provides oversight of the UC Davis Health Quality Control program for imaging devices at the Medical Center and the Primary Care Network.

Research/Academic Interests

Dr. Seibert's research focus is medical physics as applied to diagnostic imaging with emphasis on implementation and validation of digital techniques and quantitative applications in x-ray fluorography, projection imaging, mammography, CT, radiation dose, and imaging informatics to improve medical diagnosis and patient safety.
