Abstract: A magnetometer (20) comprises a magnetic field pickup coil (22) and a magnetic field detector (26) that receives electrical signals from the pickup coil (22) and produces an electrical detector output (28) responsive thereto. The pickup coil (22) and detector (26), which are preferably made of high temperature superconductors, are enclosed in an insulated enclosure (32) having no vacuum insulation structure. Preferably, the enclosure is made of a foamed polymer material such as styrofoam. A coolant is provided to the interior of the enclosure, to cool the pickup coil and detector to a temperature below their superconducting transition temperature. A number of such modular magnetometers may be connected together to form an array.

Abstract: A biomagnetometer (10) includes a magnetic field sensor unit including a magnetic field pickup coil (12). A vessel (16) contains the sensor unit. The vessel (16) includes a flexible contact face (e.g., 240) with the magnetic field sensor unit mounted in the interior of the vessel (16) adjacent to the flexible contact face. Insulation at the flexible contact face (240) of the vessel (16) prevents excessive heat flow through the flexible contact face (240). Pickup units using this structure can be connected together into flexible or rigid arrays. In operation, the pickup coil is cooled to a temperature of less than its superconducting transition temperature. A detector (30) measures the magnitude of magnetic fields sensed by the sensor unit.

Abstract: A biomagnetometer comprises an array of biomagnetic sensors, the array comprising a first plurality of magnetic field pickup coils, and a second plurality of detectors, each of which receives a pickup coil output from a pickup coil. There is a third plurality of signal processors, each of which receives an output from a detector, the third plurality of signal processors being fewer in number than the first plurality of pickup coils. The biomagnetometer further includes a selector that selects a subset of pickup coils, equal in number to the third plurality of signal processors, from the first plurality of pickup coils for signal processing by the signal processors. This biomagnetometer permits the placement of a very large array of relatively inexpensive pickup coils adjacent to a subject, and then processing information from subsets of that large array selected to optimize the gathering of data, while maintaining the cost of the signal processing electronics at a more economical level.
