Synopsis

Keywords: Bone/Skeletal, RF Arrays & Systems, Conformal Padded Posterior Array

Motivation: Conventional posterior array (PA) coils that comprise large, low-density elements housed in plastic formers with external patient pads result in SNR degradation gaps between elements and the underlying anatomy.

Goal(s): A novel, highly sensitive and conformal PA design to increase SNR and acceleration and workflow and facilitate a comfortably supported patient experience for spine and body imaging.

Approach: A prototype 30-channel conformal PA was constructed using AIR™ and foam technologies to allow the body to ‘comfortably sink’ into the foam.

Results: This novel PA demonstrated higher SNR and accommodated higher acceleration factors compared to a conventional PA.

Impact: This conformal, padded posterior array design accommodates higher acceleration and SNR for in-vivo 3T spine and body imaging.
