Abstract
A system and method for imaging a volume having a detector including a first atomic species with an absorption edge at a first wavelength. The system also includes a source having a second atomic species for emitting an ionizing energy. The second atomic species has a characteristic emission peak that substantially matches the absorption edge of the detector. A filter may be provided for blocking ionizing energy from the source in regions other than a region proximate the characteristic emission peak. Effective imaging with a lower radiation dose may be achieved with the system and method.
