    Patent number: 4625323
    Abstract: A machine for radiologically examining a patient employs a radiation source and a monochromator. The monochromator can reflect radiation from the source toward the patient. This monochromator is angularly positioned to narrow the bandwidth of the reflected radiation around a predetermined center wavelength. A discharge detector is positioned alongside the patient opposite the monochromator for producing a discharge in an electric field in response to receipt of the reflected radiation. Also included is a counting apparatus for measuring the extent of discharge in the discharge detector.
