Methods and systems for charged particle microscope confocal imaging are disclosed herein. An example method includes obtaining a plurality of probe images of a portion of a sample, each probe image of the plurality of probe images obtained at a different focal depth within the sample, applying a virtual aperture to each probe image of the plurality of probe images to form a respective plurality of confocal images, and forming a three-dimensional reconstruction of the sample based on the plurality of confocal images.
