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. Research efforts include assistance to the UC Davis Radiology Breast CT tomography project and several ongoing radiation dose awareness and monitoring projects with collaborators at other University of California Medical Centers.
As Associate Chair of Informatics, Dr. Seibert contributes to the department's implementation of electronic imaging, radiation dose monitoring, and image-processing capabilities for the UC Davis Health System. Other roles include writing specifications for new equipment, determining shielding specifications for x-ray room installations, educating physicians, radiology residents and graduate students in diagnostic imaging physics, and providing radiation dosimetry estimates for radiological examinations.
Dr. Seibert is co-author, along with other faculty in the department of the widely used 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. Previous positions include past President of the Society for Imaging Informatics in Medicine (2004-2006), and past President of the American Association of Physicists in Medicine (2010-2012). Currently, Dr. Seibert serves as a member of the National Council on Radiation Protection and Measurements (2014-2018), is on the Fellowship Committee of the American College of Radiology (2016-2017), and is a Trustee of the American Board of Radiology, representing Diagnostic Medical Physics (2013-2017).
