Inconsistent Orientation Can Be Confusing
Mastering technique in 3D/4D Z-axis rotations directly impacts our mission to deliver scans and studies that are well-defined and to facilitate accurate evaluations. By using the steps outlined within the video, you will be able to augment any 3D/4D scans to display the most common orthogonal planes that are presented in anatomy textbooks.
This does beg the question, “Why is uniform orientation of anatomy important in ultrasound volume datasets?” The short answer is that it makes recognition of anatomy easier, and elevates a reviewer’s diagnostic confidence.
It is therefore essential to produce the most clear and recognizable anatomy to minimize the possibility of misinterpretation.

If you have followed our four previous Quick Concepts on 3D/4D imaging, you may recall the importance of properly setting the region-of-interest (ROI) box, and positioning the orientation dot (or axis-point/ pivot-point).
In this video, it will become clearer why this has been emphasized. We outline ideal placements within nearly a dozen specific scanning applications and step through the procedure using a uterine scan with the endometrium as the pivot or orientation point.
