Abstract	:	Motion of a human heart is a sensitive indicator of heart disease. Magnetic resonance(MR) tagging has emerged as the gold standard for visualizing the detailed motion of a beat-ing heart. Motion is measured from tagged MR images using Harmonic Phase (HARP)-MRI, which is an image processing method that allows for fast automated processing oftagged MR images. This dissertation investigates the ability of HARP-MRI to provide sig-nificant diagnostic information. The goal of this dissertation is to translate this qualitativeclinical question into quantifiable engineering problems and to solve them.In this dissertation, we characterize both the optimal and peak performances of HARP-MRI. We study the optimal performance by investigating HARP-MRI's accuracy and byderiving protocols for its optimal use. We characterize the peak performance of HARP-MRI by deriving three performance measures: ranges of measurable motion, spatial resolu-tion, and the ability to detect small abnormalities. We also explain the presence of artifactsin the outputs of HARP-MRI, and propose an algorithm..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
