1. 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.
