Experimental CBCT imaging bench. The flat-panel detector (FPD) and the x-ray source (X) with a collimator (C) are mounted on three translation stages each (T1T3 and T4T6, respectively), allowing for precise motion along the three major axes of the imaging system. The object (Obj) is placed on a rotation stage (θ), which is mounted on another motorized translational axis (T7) and can thus be moved laterally. The bench is depicted here in a geometric configuration emulating the prototype extremities scanner. The coordinate systems of the detector (u,v) and reconstructed volume (x,y,z) are also illustrated.
