This project has proved that the MELODI concept for metal location in flesh can be realised in practice. A sensor unit has been built which performs within the bounds predicted in the initial feasibility study. The absolute accuracy was found to be generally within 2-3 mm if a target is within range. (Some targets in particular positions can return an error of up to 10 mm but this is unusual.) The volume of space that MELODI can confine a target to is 2.5x10-4 (or 0.025%) of the volume that a small conventional metal detector could confine it to. MELODI has also been successfully integrated with an ultrasound imaging machine to aid the discrimination of metals within the image. The success of the demonstration of the MELODI sensor has enabled rapid progress to be made in bringing about production to supply the NHS.
