Abstract

This paper presents a method for the simulation of sensitivity maps from an array of coils. Some of the criteria necessary for designing a coil array capable of inversion of the magnetic polarisability are examined, and sensitivity maps are analysed with this in mind. The summarised sensitivity map for a single optimised array is presented, as well as the results of noise testing of an inversion algorithm using simulated measurements.Finally, a method for the construction and testing of such an array is presented.
