In this study a dedicated rabbit heart/aorta 16-channel receive array was developed to achieve high SNR in the relevant anatomical region. A split design with two 8-ch parts was chosen. To validate the array SNR and g-factor maps were evaluated. Compared with a 15-ch knee coil the SNR of the 16-ch rabbit array was 50% higher in the center of a 2 liter bottle phantom und 2.3-fold higher in the peripheral area. The two-part design allows minimizing array-to-object distance for rabbit MRI and also simultaneously imaging of two objects with eight channels each increasing the throughput.
