<p>A method of improving the signal to noise ratio associated with the input of a digital X-ray detector (104) receiving bi-chromatic X-ray energy includes acquiring a first image from the detector corresponding to X-ray energy at a first energy level, and scaling the first image with a first scaling factor so as to produce a scaled first image. The method further includes acquiring a second image from the detector corresponding to X-ray energy at a second energy level, and scaling the second image with a second scaling factor so as to produce a second scaled image. The method also includes combining the first scaled image and second scaled image so as to form a compensated image.</p> |
