Ophthalmic Tomography Angiographic (OCT-A) Image Storage SOP Classes

Adds support for "en face" images acquired using ophthalmic optical coherence computed tomography (OCT) technology.

En Face angiography images are derived from images obtained using OCT technology (i.e., structural OCT volume images plus angiographic flow volume information).

With special image acquisition sequences and post hoc image processing algorithms, OCT angiography detects the motion of the blood cells in the vessels to produce images of blood flow in the retina and choroid with capillary-level resolution.
