Image reconstruction in digital breast tomosynthesis by total variation minimization

摘要

The total variation (TV) minimization algorithm for image reconstruction in few-view computed tomography is applied to image reconstruction in digital breast tomosynthesis. In the TV minimization algorithm, there is a parameter that regulates how close the estimated data should be to the actual projection data. The effect of this parameter on the reconstructed images is investigated. In addition, realistic noise is added to the simulated projection data.
