Computer assisted analysis of fluorescein videoangiograms.

The efficient analysis of fluorescein videoangiograms requires immediate access to any frame in a video sequence and complete control over the time base during replay. It should also be possible to compare any two frames by rapid subtraction or to subtract any phase of the study from the remaining sequence. A program that performs all these tasks has been written for a low priced desk-top microcomputer. This should facilitate the clinical introduction of fluorescein videoangiography.
