Filed:

Aug 29, 1979

Appl. No.:

6/070586

Inventors:

Chia G. Wang - Millwood NY

International Classification:

G01N 2320

US Classification:

250275

Abstract:

A method and apparatus for detecting, in a specimen, atoms, of an element having an atomic number of at least 20, comprising irradiating the specimen with monochromatic X-rays having a wavelength capable of inducing an inner shell ionization of the atoms with subsequent auger cascade and recording the emission of the auger electrons emitted by the cascade on a photographic emulsion, the monochromatic X-rays being produced by exposing a secondary radiator to X-rays to produce consequent secondary radiation in the form of the monochromatic X-rays.

Assignee:

NanoX-Medical Corp - Long Island City NY

International Classification:

A61B 6/00
A61B 6/10

Abstract:

An apparatus for low dose mammography including:(1) a monochromatic X-ray beam generator that emits a first beam of monochromatic line emission X-ray photons having an energy at or nearly above an absorption edge of a first element to induce emission of Auger electrons when the first element is irradiated with the X-ray photons; and(2) an X-ray detector including
