発明の名称 (英語) Sensor for magnetoencephalography meter and supermultichannel magnetoencephalography meter system using the same
発明の概要(英語) (US7672707)
This invention relates to a super-multichannel MEG system comprising sensors produced by printing sensor coils on thin films in positions shifted from each other and by laminating multiple thin-film sensor coils together.
Intended for use in a multichannel MEG system comprising a dewar, the sensors are arrayed in the dewar to detect biomagnetism and the Superconducting QUantum Interference Devices (SQUIDs) to detect signals coming from the sensors.
These sensors are characterized by the sensor coils being printed on thin films in positions shifted from each other laterally and longitudinally and by their being laminated in the required number.
特許請求の範囲(英語) [claim1]
1. A sensor unit for use in a magnetoencephalometer, the unit comprising: a plurality of sensor, each of which comprises a film and a sensor coil printed thereon, each of the sensor coils is arranged in a position shifted from one another laterally and longitudinally and is laminated in an overlapped manner,
wherein each of the sensor coils senses signals at a different sensing position of an object to be measured,
wherein said sensor coils are shifted in positions precisely by a length of {a}/{n} in the lateral and longitudinal directions and are laminated together in the number of {n}2, and
wherein {a} is the length of a side of the sensor coil, and {n} is a natural number.
[claim2]
2. The sensor unit of claim 1, wherein the plurality of sensors are configured to detect the difference in electric currents generated by the corresponding sensor coils and to measure the primary derivative or the high-order derivative in the axial direction of the magnetic field.
[claim3]
3. The sensor unit of claim 2, further comprising: high-speed switching corresponding to each said sensor coil in the sensor, and
superconducting quantum interference devices arranged to correspond with the high-speed switching.
[claim4]
4. The sensor unit of claim 1, further comprising: high-speed switching corresponding to each said sensor coil in the sensor, and
superconducting quantum interference devices configured to correspond with the high-speed switching.
