An x-ray collimator that may include a substrate containing a plurality of holes, each hole being frustoconical at one end and tubular at the other end for use in an x-ray imaging system, whereby the x-ray collimator may be aligned with a two-dimensional array of x-ray sources and a two-dimensional x-ray sensor, and whereby x-ray photons from the x-ray sources may pass through the collimator holes and emerge as a beam of x-ray photons in a narrow angle cone which may pass through a subject being imaged, positioned between the output holes of the collimator and the x-ray sensor.

X-ray collimator

An x-ray generator may include a plurality of electron field emitters; a target material; a plurality of energizable solenoid coils; and an electronic power and timing circuit. The generator may provide electrical current to at least one individual solenoid coil to create a magnetic field to cause the path of electrons emitted from the emitter closest to the energized solenoid coil to be defocused and/or deflected before the electrons reach the target material. The target material may comprise a low atomic number material and a high atomic number material, the high atomic number material being arranged in a regular pattern, such that, in use, the electrons may be aimed at either the high or the low atomic number material.
