    "Imaging Particles from Radioactive Decay and Applications for Medical Imaging"


    This talk will present an overview of a high-resolution imaging technology that we call iQID (ionizing-radiation Quantum Imaging Detector). IQID is sensitive to a broad range of particles emitted during radioactive decay. These include gamma-ray and X-ray photons as well as alpha, beta and neutron particles. The iQID technology combines advances in CCD/CMOS cameras, graphics processing hardware and night-vision technology for real-time imaging and position estimation of individual particles. IQID has proven beneficial in a number of medical imaging applications and was originally developed at the Center for Gamma-Ray Imaging as a high-resolution gamma-ray camera for preclinical use of single-photon emission computed tomography, or SPECT. Multicamera tomography systems are currently being developed for cancer research and small-animal brain imaging studies. Recently, iQID’s sensitivity to alpha and beta particles has spawned a new imaging capability, single-particle emission digital autoradiography, which is actively being implemented as a high-resolution imaging and microdosimetry tool for researchers investigating the use of alpha and beta particles in cancer therapy.

    Speaker Bio(s): 

    Brian W. Miller is a Linus Pauling Distinguished Postdoctoral Fellow at Pacific Northwest National Laboratory in Richland, Wash., and an adjunct assistant professor at the University of Arizona College of Optical Sciences. He received his Ph.D. in optical sciences from UA in 2011 under the mentorship of Harrison H. Barrett and Lars R. Furenlid. During his graduate studies at the College of Optical Sciences and the Center for Gamma-Ray Imaging, he focused on the development of high-resolution CCD/CMOS-based gamma-ray detectors and multicamera imaging systems for use in preclinical single-photon emission computed tomography. In 2008 he received the University of Arizona's Student Innovator of the Year Award for the development of the ionizing-radiation Quantum Imaging Detector camera. He leads iQID technology dissemination with international collaborators in Sweden, Ireland and Brazil. At PNNL, he is developing ionizing-radiation detectors and applications while continuing to develop iQID technology and expanding its applications into other fields such as digital autoradiography and microdosimetry, working with collaborators at the Fred Hutchinson Cancer Research Center in Seattle and the Johannes Gutenberg University in Mainz (Germany).
