This report presents progress in a pilot study for a new generation of tomographic walk-through metal detectors (WTMD). Although simple plane coils are not suitable for practical detectors, they provide a useful case study as coil geometries which are symmetrical are usually easier for tomography studies, where the problem can be treated as two dimensional. The work demonstrates it is possible to image the target objects of interest using 8 transmitters situated at one side operating at a single excitation frequency. With only 8 x 8 measurements, reconstructed images clearly show the correct positions of the targets.
