An MRI apparatus and method for minimizing mutual inductance between a center coil and an end coil configuration that reduces wrap-around artifacts in an MR image is provided. The switchable FOV coil configuration includes first and second RF coils aligned along a first axis. The second RF coil is coupled to the first RF coil to form a pair of end saddle coils. A central RF coil is also included having a length along the first axis and positioned at least partially within the end saddle coils such that activation of the central RF coil alone or in combination with the end saddle coils provides differing FOV's for imaging.

A magnetic resonance imaging (MRI) apparatus and method for micro-imaging is provided. The apparatus comprises an MRI system having a gradient coil positioned within a bore of a magnet that impresses a polarizing magnetic field. The apparatus also includes an RF transceiver system, having an RF switch controlled by a pulse module, to transmit RF signals to an RF coil. Upon selection of a micro-imaging scan, a computer activates a micro-imaging gradient coil positioned within the bore of the magnet. The micro-imaging gradient coils are assembled such that, upon energization, substantially linear magnetic field gradients are created along three axes in a localized FOV adjacent to the micro-imaging gradient coils.

An MRI apparatus and method for reducing wrap around artifacts during image reconstruction is provided. An RF coil and control configuration includes a center coil and at least one pair of end RF coils configured to encode and excite spins over an adjustable field-of-view (FOV). The adjustable FOV has at least two size designations in response to an FOV size request input. The control connected to the RF coil assembly is capable of switching between the FOV size designations by switching power to activate a center coil alone or the center coil in conjunction with the end coils in unison.
