Abstract
Abstract A surface electrical coil structure for use as a signal receiver and/or transmitter with the desired magnetic field characteristics and which comprises a plurality of small coils positioned over or around a specified volume each coil being singly or severally electrically connected such that the flow of electrical current within each coil produces the desired signal response or magnetic field.

A surface electrical coil structure for use as a signal receiver and/or transmitter with the desired magnetic field characteristics and which comprises a plurality of small coils positioned over or around a specified volume each coil being singly or severally electrically connected such that the flow of electrical current within each coil produces the desired signal response or magnetic field.
Claim 2
Dependent Claim
60 words
A surface electrical coil structure for use as a signal receiver and/or transmitter with the desired magnetic field characteristics and which comprises a plurality of small coils positioned over or around a specified volume each coil being singly or severally electrically connected such that the flow of electrical current within each coil produces the desired signal response or magnetic field.
Claim 3
Dependent Claim
72 words
A surface electrical coil structure as claimed in claim 1 in which the magnetic field at any point distant from the array, produced by each small coil comprising the array considered as a finite element, mimics the field at that point which would be produced by an equivalent continuous current distribution over the surface of an object which is necessary to produce the desired field at the same point within the object.
Claim 4
Dependent Claim
34 words
A surface electrical coil structure as claimed in claim 1 or claim 2 in which the signals from the coil array are received in a parallel arrangement into a single amplifier and receiver circuit.
Claim 5
Dependent Claim
33 words
A surface electrical coil structure as claimed in claim 1 or claim 2 in which the coils are connected in series and the total signal is fed into a single amplifier receiver circuit.
Claim 6
Dependent Claim
46 words
A surface electrical coil structure as claimed in claim 1 or claim 2 in which one or more of the coils in the array are connected to individual amplifiers thereby forming a plurality of receivers which may be interrogated individually or summed into a single signal.
