A 31-channel integrated “AC/DC” B0 shim and radiofrequency receive array coil for improved 7T MRI

A 31-channel integrated “AC/DC” B0 shim and radiofrequency receive array coil for improved 7T MRI

Purpose: To test an integrated “AC/DC” array approach at 7T, where B0 inhomogeneity poses an obstacle for functional imaging, diffusion-weighted MRI, MR spectroscopy, and other applications. Methods: A close-fitting 7T 31-channel (31-ch) brain array was constructed and tested using combined Rx and Δ...
