"WebThe predominant artifact that degrades FIB tomography is ion mill curtaining, where mill patterns form large aperiodic stripes in each image. The ion mill curtaining can be removed using destriping algorithms. FIB tomography can be done at both room and cryo temperatures as well as on both materials and biological samples.
