In this work we describe a single channel transmit coil and 8-channel receive array for in vivo rodent imaging on a 7 T whole-body scanner. The coil system consists of a linearly polarized, actively detuned birdcage coil for transmit and a circumferential, 8-loop actively detuned receive array with an inner diameter of 54 mm suitable for rats and other similarly sized rodents. The birdcage and the receive array are both mounted on transparent PMMA tubes for easy visual positioning and monitoring of the subject; additionally, a halogen lamp can be used to prevent cooling of the animal.
