The rotation of the image is significant because, according to Dr. Franke-Arnold it can be used to encode information, giving the technique a possible application in computing.

But simple rotation of a static 3D image is already less complex than a true movie, in which many elements can be in differential motion at the same time.

This would give you a scroll view that resized as the view controller's view resized (such as on device rotation), and the image view would be a scrolling subview.

Though the rotation takes only a few seconds, the overall image will be blurred if the patient moves.

ECONOMIST: Modern X-ray technology

Use a photographic plate to record an image from a zenith-pointing telescope, and you will end up with a streaky image, as a result of the earth's rotation.

ECONOMIST: Mirror, mirror

Use a digital sensor, however, and it is possible to shuffle the image across the sensor in such a way that it is exactly in step with the earth's rotation.
