Artifacts and imperfections that can occur illustrated on the images of P7. Blue arrows point to an aliasing artifact, which, howeher, does not affect the quality of the vocal tract imaging. Yellow arrows point to motion artifacts that take place in case of rapid change of the articulators’ position (like the transition from /l/ to /a/, and from /a/ to /k/). The white ellipse points to a tongue region with slightly lower intensity which is caused by relatively large slice thickness and tongue shape variations in the left-right direction (partial volume effects).
