The performance of the HIC glove coil, compared to three state-of-the-art LIC phased arrays (20 element head coil, 15 element knee coil, and 16 element hand/wrist coil). The top row shows pictures of the coils. The middle row shows the SNR map (on a logarithmic scale). The bottom row shows a T1 weighted image obtained with each coil (250 μm in-plane, 2mm slice thickness). The 232 mm diameter head coil provides adequate space to perform complex motions such as grasping objects, but can only deliver 20% of the SNR provided by the dedicated hand/wrist coil. The smaller knee coil (154mm diameter), which only allows finger flexing and moderate wrist motion, can deliver about 29% of the SNR. The glove coil provides complete flexibility while providing SNR similar to that of the highly-optimized rigid hand/wrist coil (97%), despite using only half as many receive channels (see also Table 1). All in-vivo SNR measurements were performed once, during a single session with the same volunteer.
