摘要：
We present a method for obtaining quantitative images from dual energy X-ray CT measurements. We adopt a statistical model for the data and reconstruct images by maximizing the log-likelihood via an alternating minimization (AM) algorithm. Results for simulated data are shown and are compared to a post-processing method.
