Title: Equipment for spectral radiology

Abstract

A medical diagnostic method is described for radiologically examining a living patient for a predetermined spectral feature indicative of predetermined absorption edges of target atoms in the living patient. The method includes a reflective monochromator having a bent, radiation reflective crystal, a source of radiation for producing x-rays at an energy range suitable for medical diagnostics and a spectrum suitable for producing images of the inside of the patient. The method comprises: directing the source of radiation at the monochromator; supporting the living patient at a position to intercept x-rays reflected from the monochromator; angularly positioning the monochromator to reflectively focus at a point in the living patient a narrowed bandwidth of the radiation with a wavelength continuously, spatially and angularly variable over a bandwidth embracing the predetermined spectral feature; and measuring on that side of the patient opposite the monochromator the extent of radiation passing through the patient at a position where the spectrum of the radiation is spatially distributed.
