Paper Abstract

A stationary x-ray source for tomographic medical imaging is being developed. The source is based upon a matrix addressable array of microfabricated cold cathodes. The characteristics of the x-ray source for breast imaging applications are being quantified. Emission currents exceeding 300 mA from 1 sqmm cathodes have been observed and currents exceeding 100 mA are now routine. X-ray focal spots on the order of 0.2 mm in diameter have been produced with currents of 25 mA @ 25 kV dc.
