An imaging system is provided for various non-invasive medical and
non-medical imaging. The imaging system includes a tunable X-ray source
for emitting X-rays having a substantially monoenergetic spectrum and an
energy discriminating detector for generating a detector output signal in
response to the X-rays incident on the energy discriminating detector.
The imaging system also includes a system controller comprising an X-ray
controller for operating the tunable X-ray source and data acquisition
circuitry for acquiring the detector output signal from the energy
discriminating detector.
