Artifacts are commonly encountered in EM image recording. There are many different types of artifacts such as noise (e.g. dark current noise) and streaking. Consequently, there are different ways to improve the quality of images to enable lower radiation dose and higher resolution imaging. For instance, noise can be reduced using iterative reconstruction, by combining data from multiple scans, by binning, by deconvolution, or by filtering.
