Jeffrey Siewerdsen

Jeffrey Siewerdsen did his undergraduate studies at the University of Minnesota in Minneapolis, MN, where he received his Bachelor of Arts degree in Physics and Astrophysics with a minor in Japanese in 1992. His undergraduate research experience included construction and testing of particle detectors for the Soudan 2 proton decay project.

Siewerdsen began graduate studies at the University of Michigan in Ann Arbor, MI, in 1992, working initially in high-energy physics (D0 experiment) under supervision of Professor Homer Neal and earning his Master of Science degree in Physics in 1994.

Siewerdsen's doctoral research involved early development of amorphous silicon Flat panel detector for medical x-ray imaging under the supervision of Professor Larry E. Antonuk. Siewerdsen's work focused on the development of early flat-panel detector systems for diagnostic radiography, fluoroscopy, and mammography as well as megavoltage portal imaging for guidance of radiation therapy. His doctoral dissertation{{Cite journal|last=Siewerdsen|first=Jeffrey H.|date=1998-11-01|title=Signal, noise, and detective quantum efficiency of a-Si:H flat-panel imagers|journal=Medical Physics|language=en|volume=25|issue=11|pages=2250|doi=10.1118/1.598427|bibcode=1998MedPh..25.2250S|issn=2473-4209|hdl=2027.42/135065|url=https://deepblue.lib.umich.edu/bitstream/2027.42/135065/1/mp8427.pdf|hdl-access=free}} established mathematical models for the signal-to-noise properties (specifically, the modulation transfer function, noise-power spectrum, and detective quantum efficiency) of flat-panel x-ray detectors. His Ph.D. thesis was awarded the Kent M. Terwilliger Prize for Best Doctoral Dissertation in Physics, 1998.

Siewerdsen conducted post-graduate research beginning in 1998 as a research scientist at William Beaumont Hospital in Royal Oak, MI, with Dr. David Jaffray and Dr. John Wong on the topic of cone beam computed tomography (CBCT) for image-guided radiation therapy (IGRT).{{Cite journal|last1=Jaffray|first1=David A|last2=Siewerdsen|first2=Jeffrey H|last3=Wong|first3=John W|last4=Martinez|first4=Alvaro A|title=Flat-panel cone-beam computed tomography for image-guided radiation therapy|journal=International Journal of Radiation Oncology, Biology, Physics|volume=53|issue=5|pages=1337–1349|doi=10.1016/s0360-3016(02)02884-5|pmid=12128137|year=2002}}{{Cite journal|last1=Jaffray|first1=D.

Siewerdsen joined the Ontario Cancer Institute and University of Toronto Department of Medical Biophysics as a scientist and assistant professor, respectively, in 2002, and subsequently as senior scientist and associate professor in 2007. Research in his laboratory focused on image-guided surgery, new imaging methods such as dual-energy imaging, and image registration.
