In-room imaging and MR planning

CAIPIRINHA: PI in Two Dimensions

• In 3D imaging, a second dimension for coil encoding is available • Sufficient coil sensitivity variations required • Strong dependence on coil (‘g factor’) • CAIPIRINHA modifies gradient or RF excitation to relax aliasing criteria
