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

摘要 脑磁图(MEG)是一种重要的功能神经成像技术，它提供了 高空间和高时间分辨率的完美结合。目前，脑磁图扫描仪存在缺陷。 由于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 完成第二阶段项目后，我们开发了适合替代产品的新型非低温光学传感器 用于MEG系统中的超导传感器。 在这个项目中，使用我们最新开发的传感器，我们将建造一种低成本、常温、可穿戴的 分辨率超过当前黄金标准的MEG系统。在这个项目中开发的系统将是 适用于神经科学研究应用的先进的商业化准备原型。

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.
