York Instruments' main product is MEGSCAN: a next-generation magnetoencephalography (MEG) brain scanner which offers non-invasive functional brain imaging with wide clinical utility including applications relating to epilepsy, concussions, and oncology. At the heart of the MEGSCAN system is new type of magnetic sensor, called the Hybrid Quantum Interference Device (HyQUID). HyQUIDs are superconducting magnetometers that are expected to have lower noise and higher sensitivity than the magnetometers traditionally used in MEG systems. Here, York Instruments will work closely with the National Physical Laboratory (NPL) to build a novel measurement platform with which the performance (HyQUID noise floor) will be verified. This will lead to further understanding and iterative optimisation of the sensor to provide best performance and ultimately improved diagnostic capability of the York Instruments MEGSCAN system.

York Instruments 的主要产品是 MEGSCAN：新一代脑磁图 (MEG) 大脑扫描仪，可提供具有广泛临床用途的非侵入性功能性脑成像，包括与癫痫、脑震荡和肿瘤学相关的应用。 MEGSCAN 系统的核心是新型磁传感器，称为混合量子干涉装置 (HyQUID)。 HyQUID 是超导磁力计，预计比 MEG 系统中传统使用的磁力计具有更低的噪声和更高的灵敏度。在这里，约克仪器公司将与国家物理实验室 (NPL) 密切合作，建立一个新颖的测量平台，用于验证性能（HyQUID 本底噪声）。这将导致对传感器的进一步了解和迭代优化，以提供最佳性能并最终提高约克仪器 MEGSCAN 系统的诊断能力。
