when measurements are performed from an iScape image.

5.12.2.5 Evaluate image quality
Many variables may affect the overall image quality. It is important to evaluate the image content and
quality before an image is used for diagnosis or measurements.
NOTE:
iScape panoramic imaging is intended for use by well-trained ultrasound operators or
physicians. The operator must recognize image items that will produce a sub-optimal or
unreliable image.
If the image quality cannot satisfy the following criteria, you shall remove the image and capture it again.
The Image must be continuous (no part of an image moves suddenly or disappears.)
No shadow or absent signal along the scan plane.
Clear profile of anatomy through the entire scan plane without distortion.
Skin line is continuous.
The images are captured from the same plane.
There are no large black areas in the image.
