Abstract
A digital x-ray imaging system employs a pixelated flat panel digital x-ray detector separated by a space from a source of x-rays which is selectively switchable between first and second, different x-ray energy levels, the space accommodating a body to be subjected to x-ray irradiation and imaging. A computer controls the x-ray source to irradiate the body with the first and second energy level x-rays and produce corresponding first and second x-ray images respectively of the first and second energy levels on the detector, the computer processing the respective digital signal outputs of the detector for the first and second digital images respectively of the first and second energy levels for each pixel, in individual succession for all pixels, and selectively produces and displays a soft tissue image or a bone/calcification image.
