BOLD EPI functional imaging at 1.5 mm isotropic resolution.

Hi resolution (1.5 mm^3) functional imaging

Six 12 sec alternations of 8 Hz reversing checkerboards at 6% contrast. No spatial or temporal smoothing. Functional data thresholded at p < 0.00001 uncorrected with minimum cluster size of 40 contiguous voxels. Note how functional activation follows the contours of the suclus.

32-Channel Structural Imaging

32-channel MPRAGE

MPRAGE data acquired at 1 mm^3 resolution with the Siemens 32-channel head coil. Acquisition time: 4:01

Signal-to-Noise Comparison: 32-Channel vs 8-Channel Head Coils

32-channel v 8-channel SNR comparison

Percent improvement for 32-channel Siemens head coil vs standard 8-channel Siemens head coil ((SNR:32/SNR:8)*100). Value of 100 equals equivalent performance; 200 indicates 2x SNR for 32-channel coil.
