    Image Science in Medical and Security Applications


    Image science is a growing field of study that attempts to understand every aspect of the imaging chain from the physical principles governing the interactions between light and matter to the evaluation of images by physicians, scientists, or algorithms.  Taking this broad viewpoint ensures that no link in the imaging chain is ignored when attempting to design imaging hardware or make optimal use of measurements in post-processing.  Traditional measures of image quality based on modulation transfer functions and noise analysis tend to analyze only a single aspect of the imaging chain.  An evaluation of the entire imaging chain is possible by considering the scientific task or tasks that are performed using the images.  Thus, to objectively define image quality, we consider the task to be performed, the image-formation process, the objects being imaged, and the observer (whether human or computer) performing the post-processing.  In this talk, I will introduce the basic concepts of image science and cover applications of the methods to two medical applications: dose reduction in computed tomography (CT) and adaptive pre-clinical imaging.  In addition, I will discuss image quality applications in treaty verification where nuclear imaging is used to verify the presence or absence of treaty-accountable items.

    Speaker Bio(s): 

    Matthew A. Kupinski is a Professor at The University of Arizona with appointments in the College of Optical Sciences, the Department of Medical Imaging, and is an affiliate member of the Program in Applied Mathematics.  He received a BS degree in physics from Trinity University in San Antonio, Texas in 1995, and received his PhD in 2000 from the University of Chicago.  In 2000 he became a post-doctoral researcher under Dr. Harry Barrett at the University of Arizona and became a faculty member in Optical Sciences in 2002.  He is the recipient of the 2007 Mark Tetalman Award given out by the Society of Nuclear Medicine and the 2012 recipient of the Graduate and Professional Student Council Outstanding Mentor Award.  He is an Associate Editor of the Journal of Medical Imaging, and currently the conference chair for the SPIE Image Perception Conference.  He has over 50 peer-reviewed publications, numerous book chapters, and has edited a book.  His current and past research funding spans the NIH, corporate projects on Medical Imaging from Canon and GE, small-company projects on biometrics, and Department of Energy funding through collaborations with Sandia National Labs and Pacific Northwest National Labs.  He has worked in diverse areas of imaging including x-ray, gamma-ray, diffuse optical, magnetic resonance, and neutron imaging.
