J. Anthony Seibert

Clinical Interests

Dr. Seibert's role at the clinical level involves acceptance testing and quality control for radiological imaging equipment used in the departments of radiology, surgery, medicine and other sites at UC Davis Medical Center and UC Davis Health System.

An expert in digital radiography, Dr. Seibert specializes in using digital techniques and quantitative applications for digital x-ray fluorography, projection imaging, mammography, computed tomography and ultrasound/magnetic resonance imaging. He also contributes to the department's implementation of electronic imaging, informatics and image-processing capabilities for the UC Davis Health System.

As Associate Chair of Informatics, Dr. Seibert assists in writing specifications for new equipment, determines shielding specifications for x-ray room installations to protect patients and staff, trains physicians, radiology residents and graduate students in diagnostic imaging physics, and provides dosimetry estimates for radiological examinations.

He is co-author, along with other faculty in the department, of a popular physics text, The Essential Physics of Medical Imaging, and is extensively involved in physics education and training. On the national scene, Dr. Seibert takes an active role in continuing professional development and education. He is the President of the American Association of Physicists in Medicine and will be the Chairman of the Board in 2012.

Activities with the American College of Radiology include service on the Commission on Medical Physics to develop guidelines and technical standards and as an item writer for the in-service exam. Dr. Seibert currently serves on the editorial board for the journal Radiology.In terms of service to certification boards, he is active within the American Board of Radiology and writes questions for the diagnostic radiological physics exam and maintenance of certification efforts, and is a trustee of the American Board of Imaging Informatics.
