The objective is to enable state of the art, high performance, cardiac magnetic resonance imaging in the pediatric population. Magnetic Resonance Imaging (MRI) has the ability to depict the heart with high spatial resolution and excellent soft tissue contrast characteristics. MRI does not employ ionizing radiation and should consequently be the medical imaging modality of choice in the pediatric population, which is especially sensitive to the harmful effects of ionizing radiation. The signal strength and imaging speed depends (in part) on the MRI receive coils (antennae). On most clinical scanners, the size and performance of these coils are optimized for the adult population and consequently it is difficult to image optimally in children with commercially available coils. This contract would address this specific problem by providing coils that are optimized for the pediatric population.

其目的是在儿科人群中实现最先进的、高性能的心脏磁共振成像。磁共振成像(MRI)具有较高的空间分辨率和良好的软组织对比特性。MRI不使用电离辐射，因此应该成为儿科人群的首选医学成像方式，因为儿科人群对电离辐射的有害影响特别敏感。信号强度和成像速度(部分)取决于MRI接收线圈(天线)。在大多数临床扫描仪上，这些线圈的大小和性能都是针对成人人群进行优化的，因此很难在使用商用线圈的儿童中进行最佳成像。这份合同将通过提供针对儿科人群进行优化的线圈来解决这一具体问题。
