Paper Abstract

We address the problem of applying Dual-Energy techniques to Image-Intensifierbased acquisition systems. We propose a new Dual Energy calibration and combination scheme, which takes into account the spatially non-uniform response of the Image Intensifier. During the calibration step, the coefficients of the combination are locally estimated for a set of uniformly spaced points over the image, and interpolated from these samples for the other points. In the combination step, the selective images are generated using the corresponding polynomia for each pixel. 3D selective reconstruction of bone-only structures is presented as a possible application. Experimental results obtained on anthropomorphic phantoms are discussed.
