Talk Title: Image Recovery and Recognition via Exploiting the Structural Bias of Neural Networks
Abstract: Deep neural networks are highly successful tools for image classification, recovery, and restoration. This success is often attributed to large amounts of training data. However, recent findings challenge this view and instead suggest that a major contributing factor to this success is that the architecture imposes strong prior assumptions-”so strong that it enables image recovery without any training data. In this talk we discuss two instances of this phenomena: First, we show that fitting a convolutional network to a corrupted and/or under-sampled measurement of an image provably removes noise and corruptions from that image, without ever having trained the network. Second, we show that it is possible to learn from a dataset with both true and false examples, obtained without explicit human annotations, by exploiting the phenomena that neural networks fit true examples faster than false ones.

Talk Title: Portable Point-of-Care Bedside MRI
Series: Medical Imaging Seminar Series
Abstract: I will describe the career path that led me from USC (B.S. B.M.E.E. 1998) to graduate school, experiences in industry to academia and back to industry again, and conclude with the most exciting stage of my career so far -“ helping to validate the clinical utility of the world's first portable point-of-care bedside MRI scanner.
Biography: Brian is a biomedical-electrical engineer (B.S. BME-E University of Southern California, 1998) whose Ph.D. training at the Mayo Clinic College of Medicine focused on biomedical imaging. Specifically, he is an expert in methods and software development for magnetic resonance imaging (MRI). His previous and ongoing work concentrates on overcoming the real-world limitations that hinder research and clinical applications of MRI. Strategies to overcome these challenges include hardware and software solutions, alternative data acquisition and reconstruction methods, novel MRI pulse sequences, quantitative imaging methods and associated post-processing tools. Based on more than 20 years of experience in MRI and 6 years of work experience as the on-site Philips Healthcare MR clinical scientist supporting research projects at Vanderbilt University, Dr. Welch acquired deep knowledge of the capabilities of the 3T and 7T human scanners housed at the Vanderbilt University Institute of Imaging Science (VUIIS). Dr. Welch applied that experience and knowledge to his own independent research programs as a Vanderbilt faculty member with contributions in the areas of fat-water MRI, human brown adipose tissue imaging, and continuously moving table MRI. Most recently, Dr. Welch joined the startup company Hyperfine in 2017 as the Director of Clinical Science with the goal of validating the clinical utility of the world's first portable point-of-care bedside MRI scanner.

Speaker: Houchun Harry Hu, Ph.D., Clinical Scientist, Hyperfine, Guilford, CT
Talk Title: Fat to Water in Pediatric MRI
Series: Medical Imaging Seminar Series
Abstract: I will share my experience and career path/choices as a MRI physicist working in three large children's hospitals, from Los Angeles (2011-2014), to Phoenix (2014-2017), to Columbus (2017-2019). I will highlight several projects, including my interests in childhood obesity, my work with spiral MRI in the clinical setting, my foray into non-Gadolinium angiography techniques and arterial spin labeling in children, and my interest in non-Cartesian free-breathing techniques. I will conclude with my thoughts on the promises of a portable point of care MRI system in pediatric settings.

He obtained his undergraduate degree (B.S., BME/BMEC) from USC in 2001, and went on to earn a PhD (2006) in BME / MRI from the Mayo Clinic in Rochester, Minnesota. From 2006-2011, he spent time in Professor Krishna Nayak's laboratory at USC working primarily on water-fat imaging. From 2011-2014, he transitioned to Children's Hospital Los Angeles to work on NIH-funded projects in brown adipose tissue. From 2014-2017, Harry moved to Arizona to work as a clinical MRI physicist at Phoenix Children's Hospital, collaborating with Dr. James Pipe from the Barrow Neurological Institute on spiral acquisitions in pediatric brain applications. In June 2017, Harry was recruited to Nationwide Children's Hospital in Columbus, Ohio, as the Director of Imaging Research. In late 2019, Harry joined Hyperfine as a Clinical Scientist as a member of Dr. E. Brian Welch's team to focus on the deployment of the company's point-of-care portable MRI systems in pediatric centers. Harry has served as a Deputy Editor for Magnetic Resonance in Medicine (2012-2017) and is currently an Associate Editor for Radiology and the Journal of Magnetic Resonance Imaging.
