Overview
FieldLine Inc. is a United States-based brain imaging device company that designs and builds magnetic sensing and imaging solutions for medical and research markets. Its flagship product is the HEDscan system, a non-invasive, wearable magnetoencephalography (MEG) platform built around the company's optically-pumped magnetometer (OPM) sensor technology. Instead of relying on large, cryogenic superconducting quantum interference device (SQUID) arrays housed in heavy magnetically shielded rooms, FieldLine places small quantum sensors directly on the head to record and map neural activity with high fidelity. The HEDscan system is designed around light-weight, wearable helmets that can accommodate people of all ages and head sizes, from infants to adults. Because the sensors are non-cryogenic and compact, the device can be used in any room of any medical facility without the need for expensive building modifications, and it works with small magnetic shields. The platform is scalable, supporting up to 512 OPM sensors in a high-density configuration, and is described as plug-and-play, allowing fully integrated, minutes-to-data collection. FieldLine markets the system for applications including brain-computer interfaces (BCI) as well as clinical and cognitive neuroscience research. FieldLine was founded by three specialists in quantum sensing and atomic physics: Orang Alem, Svenja Knappe, and Jeramy Hughes. Alem has spent much of the 21st century designing, developing, and troubleshooting some of the world's most sensitive optically-pumped magnetometers, with a focus on bringing OPM technology to medical and research markets. Knappe has worked on miniaturized OPMs and microfabricated quantum sensors for over 20 years across academia, government, and industry; she holds a PhD in physics and a faculty appointment in the Mechanical Engineering Department at the University of Colorado, Boulder. Hughes is an inventor with an entrepreneurial background in atomic physics who has helped bring nearly a dozen quantum devices to market. The company is privately held and operates from Boulder, Colorado, a hub for quantum and atomic-physics research. Its product line includes the HEDscan system, magnetic shields, and high-density helmets, all listed as available. FieldLine positions itself at the intersection of quantum sensing and neuroimaging, aiming to make MEG more accessible, wearable, and practical for a broad range of clinical and research settings.
History
FieldLine Inc. is an American brain imaging device company built around optically-pumped magnetometer (OPM) technology. The company was founded by three specialists in quantum sensing and atomic physics: Orang Alem, Svenja Knappe, and Jeramy Hughes. Their combined experience spans the design, development, and troubleshooting of some of the world's most sensitive OPMs, miniaturized quantum sensors, and the commercialization of quantum devices. Orang Alem has spent a good part of the 21st century designing, developing, and troubleshooting some of the world's most sensitive optically-pumped magnetometers, focusing on bringing OPM technology to the medical and research markets. Svenja Knappe has worked on miniaturized OPMs and microfabricated quantum sensors for over 20 years across academia, government, and industry; she holds a PhD in physics and a faculty appointment in the Mechanical Engineering Department at the University of Colorado, Boulder. Jeramy Hughes is an inventor with an entrepreneurial spirit and a background in atomic physics; he has been part of a number of startup companies and helped bring nearly a dozen quantum devices to market. The company's core innovation is the application of small, non-cryogenic quantum sensors to magnetoencephalography (MEG). Traditional MEG systems rely on large, cryogenic SQUID sensor arrays that require heavy magnetically shielded rooms and expensive building modifications. FieldLine's HEDscan system instead places compact OPM sensors directly on the head, enabling a wearable, light-weight helmet design that accommodates people of all ages and head sizes. The system is scalable to up to 512 sensors, is described as plug-and-play with minutes-to-data collection, and can be used in any room of any medical facility with only small magnetic shields. FieldLine markets the HEDscan system for clinical and research neuroimaging as well as brain-computer interface (BCI) applications. The company offers the HEDscan system, magnetic shields, and high-density helmets, all listed as available. FieldLine is privately held and based in Boulder, Colorado, a center of quantum and atomic-physics research.
