Accelerated Computing in Magnetic Resonance Imaging: Real-Time Imaging Using Nonlinear Inverse Reconstruction
Table 2
Reconstruction times in fps for various image sizes with side length and fixed versus variable oversampling ratio . For some input sizes, is the optimal value (, ); for other sizes, the number of grid sample locations must be increased to yield a speed-up (, ). For a third group of image sizes (), the optimal FFT size increases the size of the data to a degree that the speed-up is reduced or even nullified by additional overhead. For each test case, 200 frames were reconstructed using 1 accelerator.
