The performance of a liquid nitrogen cooled receive-only copper coil to acquire micron scale high resolution mouse imaging on a 3T whole body scanner is investigated. In this work a novel cryostat design, which provides easy access for small animal samples, is described. The receive coil is a 2 cm diameter copper coil with active decoupling during transmission. The Q factor of the coil has been enhanced by 60% after cooling down for 1 hour to reach 120 K, and the SNR performance has increased by 2 fold compared with the room temperature version of the same coil.
