The process of identifying the inscriptions used by the Antikythera Mechanism Research Project (AMRP) involved the use of optical and x-ray microfocus computer tomography imaging. Project members went to the National Archaeological Museum in Athens where the pieces of the Antikythera Mechanism are stored. There, the AMRP and museum staff examined the exterior surfaces of the Mechanism, using a technique of "reflectance imaging" developed by Tom Malzbender and colleagues at Hewlett-Packard (USA). The team carried out high-resolution three-dimensional X-rays, using a technique called "microfocus x-ray computed tomography", a method developed by Roger Hadland and his team from X-Tek Systems (UK).
