US Artifacts: Effects on Out-of-Plane US Images Reconstructed from Three-dimensional Data Sets¹

Three-dimensional volumetric data sets of stacked ultrasonographic (US) scans were obtained in vitro and in vivo to investigate the effect of common US artifacts on cross-sectional images reconstructed out-of-plane to the plane of acquisition of these data sets. The appearance of the artifacts on the reconstructed images was different from that on the source images. Such artifacts have the potential to simulate pathologic abnormalities.
