BF-(S)TEM Tomography Software


Summary

While Bright Field-Electron Tomography (BF-ET) is very popular in the biological sciences, its use in the physical sciences is limited because the measurements are affected by Bragg scatter (and other anomalies) leading to contrast reversals. In this work, we propose a model that takes into account the occurrence of these anomalies in the MBIR framework. We then develop an efficient algorithm based on functional substitution/majorization/surrogate functions to minimize the MBIR cost. The algorithm works well with both crystalline and amorphous samples and can be very useful for low-dose imaging.
