A system for non-destructive evaluation of an object uses a spherical coordinate system to control two robotic arms. In some examples, the system includes a radiation source coupled to one robotic arm, a radiation detector coupled to the other robotic arm; and a control unit configured to determine, based on input, a first position located on a first surface of a first sphere within the spherical coordinate system; determine, based on the input, a second position located on a second surface of a second sphere within the spherical coordinate system, wherein the second position is located opposite a midpoint of the spherical coordinate system from the first position; and control a motion of the source robotic arm and the detector robotic arm such that the radiation source and the radiation detector move to different ones of the first position and the second position.

An apparatus () provides for tuning of an effective focal spot size of a radiation source. The apparatus may comprise a plurality of inter-channel structures () defining a plurality of channels () passing through the apparatus from a first surface () to a second surface (). The inter-channel structures comprise a first substance and the channels contains a second substance. The first substance attenuates radiation more than the second substance. The inter-channel structures may define the channels such that lines passing through the channels converge at a location on or near the surface of a focal spot ().
