High-resolution Non-cryogenic Magnetoencephalography: Systems-Level Integration

摘要 脑磁图（MEG）是一种重要的功能性神经成像技术， 高空间分辨率和时间分辨率的完美结合。目前，脑磁图扫描仪 低温冷却超导传感器技术带来的成本和复杂性。在我们最近 完成第二阶段的项目，我们开发了新的非低温光学传感器，是合适的替代品 用于MEG系统中的超导传感器。 在这个项目中，使用我们新开发的传感器，我们将建立一个低成本，室温，'可穿戴' 分辨率超过当前黄金标准的MEG系统。本项目开发的系统将 一个先进的商业化准备原型适合神经科学研究应用。

Abstract Magnetoencephalography (MEG) is an important functional neuroimaging technique that provides an excellent combination of high spatial and temporal resolution. At present, MEG scanners are handicapped by cost and complexity imposed by cryogenically cooled superconducting sensor technology. In our recently completed Phase II project, we developed new noncryogenic optical sensors that are suitable replacements for superconducting sensors in MEG systems. In this project, using our newly developed sensors, we will build a low cost, room temperature, ‘wearable’ MEG system with resolution exceeding current gold standards. The system developed in this project will be an advanced commercialization ready prototype suitable for neuroscience research applications.
