20120170718 | APPARATUS FOR PRODUCING X-RAYS FOR USE IN IMAGING - An apparatus for producing x-rays for use in imaging applications having a piezoelectric or pyroelectric crystal with an upper surface and a conducting film coating the upper surface. The crystal includes a plurality of field emitters formed as micrometer-scale exposed regions in the crystal having a one or more sharp peaks or ridges, or parallel trenches forming a wedge shaped emitter. The crystal is alternately heated and cooled over a period of-time so that spontaneous charge polarization occurs in the crystal. The spontaneous charge polarization causes a perpendicular electric field to arise on the crystal's top and bottom faces, that is enhanced by the sharp peaks or ridges, thereby causing field emission of surface electrons from that location. X-rays are produced when the emitted electrons strike a target material located adjacent to the emitting face, and the X-rays may be filtered or collimated. | 07-05-2012 |
