· The goal <strong>of</strong> my work is to design highly accelerated free breathing perfusion and delayed enhancement<br />
cardiac MRI acquisition schemes. The motivation is to utilize the gain in speed to provide improved<br />
image quality for an accurate quantification <strong>of</strong> perfusion and viability. Efforts are underway to design<br />
these schemes, which learn the nature <strong>of</strong> temporal variations directly from the measurements. We look<br />
to leverage the benefits <strong>of</strong> k-t space models, matrix recovery, compressed sensing and parallel imaging<br />
in designing our acquisition schemes.<br />
