Abstract: Disclosed here is a scanning probe microscope system and method for operating the same for producing scanning probe microscope images at fast scan rates and reducing oscillation artifacts. In some embodiments, an inverse consistent image registration method is used to align forward and backward scan traces for each line of the scanning microscope image. In some embodiments, the aligned forward and backward scan traces are combined using a weighting factor favoring the scan trace with higher smoothness. In some embodiments, the scanning probe microscope image is a potentiometry map and a method is provided to extract from the potentiometry map a conductivity map.

Abstract: A system for constructing images representing a 4DCT sequence of an object from a plurality of projections taken from a plurality of angles with respect to the object and at a plurality of times, first portions of the object being less static than second portions of the object. The system may comprise a processor configured to: iteratively process projections of the plurality of projections for a plurality of groups, each group comprising projections collected while the first portions of the object are in corresponding locations, with each iteration comprising: reconstructing first image portions representing the first portions of the object, the reconstructing of each first image portion of the first image portions being based on projections in a respective group of the plurality of groups; and reconstructing a second image portion, the second image portion representing the second portions of the object, based on projections in multiple groups of the plurality of groups and on the reconstructed first image portions.
