DESCRIPTION (provided by applicant): The goal of this project is to develop a very low-cost whole-head neonatal MEG system that can adapt to the shape and size of the head. Clinically, there is a longstanding need for a technology that can aid in the diagnosis and prognosis of babies with brain dysfunction due to intrauterine and postnatal central nervous system insults, which may result in mental retardation and neurodevelopmental disorders. The proposed system is completely non-invasive and is based on a recent breakthrough in atomic magnetometer technology that eliminates majority of the costs and complexity associated with superconducting sensors used in traditional MEG systems. PUBLIC HEALTH RELEVANCE: MEG is one of the most promising functional imaging techniques that have been applied to neonatal and infant studies. The goal of this project is to develop a MEG system that is ideally suited for infant studies and costs less by almost an order of magnitude - $200k to $300k compared to >$2M for a SQUID-based system. We expect that successful execution of this project will stimulate research in neonatal and infant MEG and encourage many more researchers and clinicians to adopt MEG technology.

描述（由申请人提供）：该项目的目标是开发一种成本非常低的全头新生儿脑磁图系统，可以适应头部的形状和大小。临床上，长期需要一种技术来帮助诊断和预后因宫内和产后中枢神经系统损伤而导致脑功能障碍的婴儿，这可能导致智力低下和神经发育障碍。所提出的系统是完全非侵入性的，并且基于原子磁力计技术的最新突破，该技术消除了与传统 MEG 系统中使用的超导传感器相关的大部分成本和复杂性。 公共卫生相关性：MEG 是最有前途的功能成像技术之一，已应用于新生儿和婴儿研究。该项目的目标是开发一种非常适合婴儿研究的 MEG 系统，与基于 SQUID 的系统 >200 万美元相比，成本降低了近一个数量级 - 20 万至 30 万美元。我们预计该项目的成功执行将刺激新生儿和婴儿 MEG 的研究，并鼓励更多的研究人员和临床医生采用 MEG 技术。
