Abstract:
1. A scanning bone densitometer comprising: an x-ray source configured to produce x-rays; an x-ray detector configured to receive x-rays emitted from the x-ray source, the x-ray detector including a cadmium tellurium (CdTe) semiconductor detector element, wherein the CdTe semiconductor detector element comprises an anode and a cathode, the anode comprising at least one of an indium material or an aluminum material and the cathode comprising a platinum material; and a controller configured to move the x-ray source and the x-ray detector along a transverse scanning path to acquire a plurality of scan images of an object of interest, wherein the transverse scanning path comprises a first path transverse to a longitudinal axis of the object of interest, a second path parallel to the longitudinal axis of the object of interest, and the transverse scanning path repeatedly alternates between the first and second paths.
