Geometry and energy constrained projection extension.

CONCLUSION: We establish a dual-constraint-based optimization model and correspondingly develop an accurate extrapolation method for partially truncated projections. The proposed method can be readily integrated into the clinical workflow and efficiently solved by using one-dimensional optimization algorithm. Moreover, it is robust for noisy cases with various truncation and can be further accelerated by GPU based parallel computing. PMID: 30040792 [PubMed - as supplied by publisher]
