Larry E Antonuk, PhD is the principal investigator of the Flat Panel Imager Group and a Professor in the Physics Division within the Department of Radiation Oncology of the School of Medicine, located on the Medical Campus of The University of Michigan in Ann Arbor. He is also affiliated with the Biomedical Engineering Department within the College of Engineering at the University.

Following his PhD and postdoctoral nuclear physics studies in Canada, Switzerland, and France, Dr. Antonuk came to the University of Michigan in 1987. There he founded the Flat-panel Imager Lab, and his early research focused on the design, fabrication and empirical characterization of active matrix, flat-panel imagers (AMFPIs) – a technology based on thin-film electronics that has become ubiquitous in medicine. His lab focuses on the development of technologies offering order-of-magnitude improvement in performance compared to existing projection and volumetric x-ray imagers for medical applications such as radiotherapy, radiography, fluoroscopy, breast imaging, cardiac and interventional imaging, as well as destructive and non-destructive testing.

Our research concentrates on development of the two major components of a flat-panel x-ray imager: the large-area, monolithic, solid-state backplane which takes the form of a two-dimensional matrix of imaging pixels whose thin-film circuitry is a focus of the research; and the converter positioned over the backplane where incident x-rays interact and which consists of either a scintillator or a photoconductor.

Investigating x-ray imaging technologies for applications such as radiotherapy, radiography, fluoroscopy and breast imaging, as well as cardiac and interventional imaging.
