Accelerated Dynamic MRI using Sparse, Low-Rank, and Manifold Models
Thu, Aug 13, 2015 @ 10:30 AM - 11:30 AM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Prof. Mathews Jacob, University of Iowa
Talk Title: Accelerated Dynamic MRI using Sparse, Low-Rank, and Manifold Models
Series: Medical Imaging Seminar Series
Abstract: The acquisition of dynamically evolving objects plays a central role in several MRI applications. The slow nature of MR image acquisition often makes it challenging to acquire the datasets with high spatio-temporal resolution and coverage. In this talk, efficient low-rank and blind compressed sensing algorithms to recover the datasets from highly under sampled measurements will be introduced. These methods learn the representation from the data itself, thus offering improved image representations; algorithms that rely on these adaptive representations will translate to better reconstructions. Image and patch manifold algorithms, which enables implicit motion resolved and motion compensated reconstructions will also be introduced for free breathing dynamic MRI applications

Seeing Sleep: Real-Time MRI Methods for the Evaluation of Sleep Apnea
Mon, Aug 17, 2015 @ 10:00 AM - 11:00 AM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Ziyue Brian Wu, Electrical Engineering Department, University of Southern California
Talk Title: Seeing Sleep: Real-Time MRI Methods for the Evaluation of Sleep Apnea
Abstract: Sleep apnea is a largely neglected disease, which can lead to serous consequences. Current gold standard of diagnosing sleep apnea is an overnight polysomnography, from which an apnea-hypopnea index (AHI) is derived to indicate the severity of apnea. However, lack of direct anatomical information often limits the value of such sleep studies. MRI is a great imaging tool to provide such information but also has its own challenges, namely acquisition speed, acoustic noise and cost. This talk will cover some recent developments to address these issues. Both technical improvements and clinical findings will be discussed.
Biography: Ziyue "Brian" Wu joined the Magnetic Resonance Engineering Lab at USC as a PhD student in 2011. Brian has been working on imaging sleep apnea using MRI since then under Dr. Krishna Nayak. His research focus is fast real-time MRI including novel pulse sequence design and image reconstruction. Brian is also the recipient of 2015 Grodins Graduate Award, Wallace H. Coulter Award (USC) and ISMRM summa cum laude Award.

Communications, Networks & Systems (CommNetS) Seminar
Wed, Aug 26, 2015 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Aditya Mahajan, McGill University
Talk Title: Mean Field Teams
Series: CommNetS
Abstract: In many decentralized control systems, in particular, those arising in smart grids and communication networks, the dynamics of an agent are influenced by the state of the others only through the mean-field of the population.
We investigate team optimal control of such systems. By exploiting the exchageability of the agents, we identify an information state and use it to obtain a dynamic programming decomposition of the system. Our solution provides team optimal solution for systems with arbitrary number of agents. The complexity of the solution increases exponentially with the number of agents that allows us solve systems with moderate (100s to 1000s) number of agents.
