Pediatric MR imaging currently uses adult RF coils which reduces the quality of pediatric images considering the large field of view and low signal to noise ratio (SNR). Thus there is a growing need for developing and evaluating specialty coils targeting pediatric patients. The current study focused on the design, development and evaluation of infant cardiac array RF local coil for magnetic resonance imaging of the heart of infant patients. The design criteria were identified and the coil was designed taking into account the safety considerations for the targeted patient population. This study successfully evaluated the performance of the infant cardiac array RF coil based on two most significant MR imaging parameters, SNR and imaging resolution, on a 1.5T commercial MR scanner. The increase in SNR and improvement in the resolution of images using the infant cardiac array over an existing commercially available adult coil was established using different kinds of phantom (7L, 2L, orange and lime) studies. The results revealed that there was an increase of 140% in SNR using infant cardiac array compared to the commercially available adult coil and the high resolution (<200 microns) images obtained confirmed the efficacy of the infant cardiac array coil. Thus, the infant cardiac array RF coil provides enhanced performance and high quality MR images for infant clinical applications compared to the commercial adult coils.
