Method of and system for improving the signal to noise characteristics of images from a digital X-ray detector receiving bi-chromatic X-ray energy |
摘要 |
A method of improving the signal to noise ratio associated with the output of a digital x-ray detector 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 the second scaled image so as to form a compensated image.
