Claim:
1. A detection system for locating and characterizing an object within a detection area in a three-dimensional space comprising: a plurality of magnetic field generators, comprising a plurality of transmitter coils, arranged on at least a first side of the detection area; a plurality of magnetic field detectors, comprising a plurality of receiver coils, arranged on at least a second side of the detection area, wherein the second side is opposite to the first side; a control system for generating a magnetic field in the detection area by the magnetic field generators and for measuring a modified magnetic field at each of the magnetic field detectors, wherein the generated magnetic field is modified by the object; and at least one processor configured to process the measured modified magnetic field to obtain a data set characterizing the object and a location of the object, wherein said at least one processor is configured to execute a plurality of instructions defining a reconstruction process on a predefined number of measurements of the modified magnetic field, wherein the plurality of transmitter coils and the plurality of receiver coils has been configured by quantifying an error in a predicted object location and an error in a predicted magnetic polarisability dyadic of the object as a function of a signal-to-noise ratio (SNR) of signals from the receiver coils and wherein said errors are used to configure said physical coil configuration.
