physicians. The operator must recognize image artifacts that will produce a
sub-optimal or unreliable image.
The following artifacts may produce a sub-optimal image. If the image quality cannot meet
the following criteria, you shall delete the image and do image acquisition again.
The Image must be continuous (no part of an image moves suddenly or
disappears.)
