Abstract
This invention relates to magnetic inductance tomography, and in particular, to coils of a sensor/driver coil array for use in a magnetic inductance tomography apparatus, in which driver/sensor coils are used to measure the induced flux in a conductive, dielectric and permittivity body, such as the human body. The sensor/driver coil array comprises at least one layer of thin coils whose centers are arranged on a regular grid, with adjacent coils overlapped by a suitable distance to cancel inductive neighbor coupling between them.
Claims8
A sensor/driver coil array for use in magnetic inductance tomography comprising two layers of thin coils, each layer comprising a plurality of thin coils whose centres are arranged on a regular grid, with adjacent coils in a layer being overlapped by a suitable distance to cancel inductive neighbour coupling between them, and wherein each coil in the first layer is paired with a respective coil in the second layer and the pairs of coils are anti-parallel connected and arranged at such a distance apart that they compensate each others' fields and thereby reduce external coupling effects.
