A film video processor for the viewing of fluorescein angiograms.
نویسنده
چکیده
A new, commercially available, and inexpensive film video processor facilitates the viewing of fluorescein angiograms on video monitors. The negative film is inserted into a film carrier, read by a charge-coupled device solid state pickup device and presented as a negative or positive image on a black-and-white monitor with the help of a negative/positive conversion feature. Details of the angiogram are studied by zooming into any part of the image, which magnifies the image up to six times. Contrast and brightness adjustment on the video monitor allows examination of under- or overexposed angiograms.

متن کامل[Simultaneous digital indocyanine green and fluorescein angiography].
BACKGROUND The simultaneous recording of indocyanine green and fluorescein angiography is since more than twenty years possible. The real-time digital recording of angiograms is about since 10 years possible. Because of the poor temporal resolution due to technical limitations, both of the above methods were only seldom used routinely. Graphics workstations can digitize and store multiple video...
متن کاملCorneal topography using computer analyzed rasterstereographic images.
This paper describes a new method for determining corneal surface detail utilizing a modified Zeiss photo slit lamp. This system projects a grid onto the cornea through a cobalt blue filter. The tear film is stained with fluorescein, causing the projected grid pattern to be visible on the corneal surface. A video image of the grid is then digitized by an image processor which calculates surface...
متن کاملLight-pen computer processing of video image for the determination of left ventricular volume.
A volume angiography system for on-line computation of left ventricular angiograms has been developed utilizing a video disc recorder, a light-pen unit, and a digital computer. The video disc recorder allows for immediate replay and stop-motion of ventricular angiograms on a video monitor. The light-pen is used by a technician/physician operator to define the margins of the ventricular chamber ...
