Compressed Sensing for fMRI: Feasibility Study on the Acceleration of Non-EPI fMRI at 9.4T

Figure 10

Comparison of fMRI maps reconstructed using Algorithm 2 (k-t FOCUSS with KLT). fMRI maps of CS reconstructed data using Algorithm 2 and (a) , (b) , (c) , and (d) are shown for significance level of 0.05. Downsampling pattern and acquisition method used are shown on the top and left-hand side of the images, respectively. Notice the activation foci shift (white arrow) in the phase-cycled bSSFP data. The case from a representative rat is shown since similar results were obtained for different subject rats.
