چکیده

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.

[Simultaneous digital ICG and fluorescein videoangiography with the personal computer].

BACKGROUND Since the invention of the simultaneous ICG and fluorescein (SIF) videoangiography in 1995 none of the available SLOs were significantly improved. Digital video recording with a PC can simplify and improve the quality of the angiography. METHOD SIF angiography images of a two-wavelength scanning laser ophthalmoscope were digitized with a personal computer and written to disk with a...

P-106: The Computer-Assisted Vacuolated Sperm Analysis and Zygote Quality

Background: Digital image processing and analysis are used for computer assisted evaluation of sperm morphology. Sperm head morphology has been identified as a characteristic that can be used to predict a male’s semen quality. On the other hand, zygote competence analysis is an importance tool to select embryo(s) for transfer. The aim of the present study is to determine zygote quality resulted...
