Time-Of-Flight with Sparse undersampling (TOFu): towards practical MR applications of the Compressed Sensing

TOFu. Note that venous flow is evident in TOFu due to insufficient TSat application with the current 1-per-shot scheme. Figure 1: ky-kz plot of a variable density spiral phyllotaxis trajectory for the representative TOFu imaging slab, with net acceleration factor 3.8, 21 shots and 94 segments per shot. The blue dots represent acquired points on a regular Cartesian grid, while the green dots show skipped points. Each shot (brown line) begins near the center of the ky-kz plane at one of the red dots, and then spirals outward. 3528 Time-Of-Flight with Sparse undersampling (TOFu): towards practical MR applications of the Compressed Sensing Yutaka Natsuaki, Xiaoming Bi, Michael Zenge, Peter Speier, Peter Schmitt, and Gerhard Laub Siemens Healthcare, Los Angeles, CA, United States, Siemens AG Healthcare Sector, Erlangen, Germany, Siemens Healthcare, San Francisco, CA, United States
