Device to Produce X-Rays for Use in Imaging (Case No. 2009-627)
Summary Researchers at UC San Diego have developed a compact, addressable flat-panel x-ray source based on pyroelectric / piezoelectric crystals with integrated field emitters. The design produces electron emission by temperature (or stress) cycling of crystals, which then strike a target to generate x-rays. The array architecture enables selectable...
