Magnetic Resonance Imaging Sensing and Reconstruction: A Niche Paradigm of Computational Sciences

When: Monday, November 20, 2017
Where: PGH 232
Time: 11:00 AM – 12:00 PM

Speaker: Dr. Nikolaos Tsekos, University of Houston

Host: Dr. Jaspal Subhlok

The phenomenon of magnetic resonance, that was first measured and described by Rabi in 1944, is the foundation of magnetic resonance imaging (MRI) that was introduced in 1973. MRI is a powerful modality offering a plethora of contrast mechanisms for assessing morphology and function that has shaped modern diagnostic and interventional medicine. The scientific and clinical impact of MR has led to four (4) Nobel prizes associated with it. What makes it, however, unique is that a piece of code running in an MRI scanner manipulates quantum species (nuclei) inside the human body to generate an image! One may claim that this is the ultimate cyber-physical laboratory! The code is this heart of MRI that can be modified at will; today, control of the MRI scanner and image formation pertain to a wide range of CS disciplines: real-time & embedded systems, HPC and st recently ML and VR/AR. We will discuss the MR phenomenon, image generation and reconstruction to illustrate the power of computing in the ever-growing field of MR in medicine.

Bio:

N.V Tsekos interests are focused on cardiovascular and interventional magnetic resonance imaging. Before joining the UH he was faculty at the department of Radiology at the Washington University in St. Louis, and before that at the department of Radiology at the University of Minnesota (UMN) and the Center for Magnetic Resonance Research in Minneapolis.
