Abstract :
For the reduction of exposure dose in contrast media detection with X-ray transmission measurements, the energy measurement of X-rays and the energy subtraction (ES) method have been shown to be effective. To make the ES method applicable, a novel detector for unfolding the X-ray energy distribution was proposed by the authors. As an application of this novel detector, a CT image was reconstructed with ES data and compared with the image reconstructed using electric current data.
