摘要：
Methods, devices and systems for one or both of two- or three-dimensional location of the disposition of a sensor coil in a subject including: an array of electromagnetic drive coil sets, each set having two or three dimensionally oriented drive coils a sensor coil being electromagnetically communicative with the array of electromagnetic drive coil sets and, a system controller communicative with and adapted to energize one or more of the electromagnetic coils in the array of electromagnetic drive coil sets, the energizing of the one or more of the electromagnetic coils including one or more of energizing the coils singly, or in pairs of x-y and y-z or x-z coils, or in triplets of x-y-z coils while measuring the response of the sensor coil whereby the system uses the measurements of the responses of the sensor coil to calculate the location and orientation of the sensor coil relative to said drive coil sets.
