  Speaker: Dr. Yoon Kim, University of Southern California
  
  Talk Title: Rapid MRI for Sleep Apnea and Speech Production Research
  
  Series: Medical Imaging Seminar Series
  
  Abstract: The human upper airway serves important functions such as speech, deglutition, and respiration. Understanding the nature or disorder of the upper airway functions has been of great interest in speech scientists, linguists, otolaryngologists, sleep medicine physicians, etc. MRI is noninvasive and has provided spatio-temporal information on the shaping of the tongue, soft palate, lips, and posterior/lateral pharyngeal walls with high frame rate (~20 fps).
  
  In this talk, I will introduce our technical developments for the two NIH R01 projects: 1) dynamics of vocal tract shaping and 2) phenotyping of sleep-disordered breathing in pediatric obesity using dynamic MRI. On rapid MRI of speech, the talk will be an overview of 1) speech MRI acquisition environment, 2) novel acquisition techniques in real-time 2D, high-resolution 3D, and dynamic 3D imaging, and 3) various applications of real-time speech MRI. On rapid MRI of sleep, the talk will focus on 1) our sleep MR imaging protocols, 2) upper airway compliance measurement during inspiratory loading and 3) demonstrations of airway narrowing/collapse patterns during natural sleep in overweight and obese adolescents with sleep-disordered breathing.
  
  Biography: Yoon Kim received his PhD in Electrical Engineering from USC in 2010. He is a postdoctoral research associate at USC from 2011 to 2013, working in the Magnetic Resonance Engineering Lab directed by Prof. Krishna Nayak. His research focuses on MRI pulse sequence design and image reconstruction for upper airway imaging and cardiac imaging. He is a recipient of American Heart Association postdoctoral fellowship award.
