Bio Statement

William Geiser, MS DABR, is a Senior Medical Physicist in the Department of Imaging Physics at the University of Texas MD Anderson Cancer Center. He is the Mammography Quality Standards Act (MQSA) physicist of record for MD Anderson Cancer Center Section of Breast Imaging.

After obtaining his Masters of Science in Imaging Medical Physics at the University of Florida in 1996, he began his career as clinical medical physicist working with the Environmental Health and Safety program at the University of Florida. While there he performed medical physics services for Shands Hospital at the University of Florida and obtained his board certification in Diagnostic Radiological Physics in May 2000. He moved to Texas to work at the University of Texas MD Anderson Cancer Center in December of 2001 where he currently practices as a Senior Medical Physicist in the Department of Imaging Physics.

Mr. Geiser area of expertise is in imaging physics as it relates to breast imaging. He is particularly interested in full field digital mammographic imaging and digital breast tomosynthesis. Another passion of his is image informatics and image display.

Mr. Geiser has authored several articles in peer reviewed journals, lectured at international conferences and participated as an instructor in hands on courses. He has authored a book chapter on artifacts in digital mammography.
