Abstract

Methods and systems for conducting tomographic imaging microscopy of a sample with a high energy charged particle beam include irradiating a first region of the sample in a first angular position with a high energy charged particle beam and detecting emissions resultant from the charged particle beam irradiating the first region. The sample is repositioned into a second angular position such that the second region to be different than the first region, and a second region of the sample is irradiated. Example repositioning may include one or more of a translation of the sample, a helical rotation of the sample, the sample being positioned in a non-eucentric position, or a combination thereof. Emissions resultant from irradiation of the second region are then detected, and a 3D model of a portion of the sample is generated based at least in part on the detected first emissions and detected second emissions.
