Abstract
Nuclear magnetic resonance (MR) imaging can include use of an electrical transceiver coil system comprising an array of segmented loops. The array can be arranged about a portion of an imaging subject and arranged to provide surgical access to a region of the imaging subject from at least one direction. The segmented loops can establish a volumetric radio frequency (RF) excitation field across a volume-of-interest associated with the imaging subject in response to the segmented loops receiving specified transmit phases providing a non-90-degree relative phase between segmented coil loops at adjacent ones of the segmented loops. All or at least some of the segmented loops can provide outputs indicative of an RF signal from the imaging subject, the RF signal elicited in response to RF excitation. The transceiver coil system can facilitate pre-operative, intra-operative, or post-operative MR imaging, such as facilitating access for a surgical procedure.
