Seminar title: Imaging of Flow and Motion: Noninvasive Assessment of Cardiovascular and Pulmonary Function
In this talk, an overview of our activities in several areas of biomedical imaging as relates to imaging of flow and motion will be given:
I. MRI has the unique ability to create tag saturation patterns in the myocardium through application of non-selective RF pulses prior to conventional imaging. We have been developing a set of techniques to determine 3-D regional myocardial strains from 4-D tagged MRI data. First part of the talk will be devoted to this topic.
II. The phase of the MR signal is motion sensitive - spins in the presence of an external magnetic field gradient will accumulate a phase offset from which velocity of moving tissues and blood can be determined. However, the data is noise and artifact prone. In the second part of the talk, we will describe an in-vitro flow testbed which we have developed over the last few years which allows for validation of MRI methods. Recent work in the area of 4D MR imaging of flow will also be presented.
III. In the area of 4D CT, we have developed methods for assessment of regional function of the lung and have proposed new deformable registration methods based on 3D optical flow for volumetric analysis of regional lung strains. The third part of the talk will overview results from these efforts.
Dr. Amini received his BS in Electrical Engineering from the University of Massachusetts at Amherst in 1983 with high honors where at 18 he was the youngest member of his graduating class. He received an MSE in Electrical Engineering in 1984 and his PhD in Electrical Engineering from the University of Michigan, Ann Arbor in 1990. After Postdoctoral work in Biomedical Imaging at Yale University he was on Yale faculty for 4 years. He then joined Washington University to establish his own laboratory where he stayed for 10 years. He joined the University of Louisville Electrical and Computer Engineering Department in 2006 as Endowed Chair in Bioimaging and full professor with support from the Kentucky Research Challenge Trust. Dr. Amini is active in IEEE Engineering in Medicine and Biology Society where he serves on its Ad Com, is on the editorial boards of IEEE Transactions on Medical Imaging and IEEE Transactions on Biomedical Engineering and will chair the international symposium on Biomedical Imaging which will take place in Washington, D.C. in 2018. His research has been funded by the NSF, NIH, and several private foundations. He was elected a Fellow of the IEEE Engineering in Medicine and Biology Society in 2007.
