    The appropriate storage and archiving of angiographic images and
    data still represents a major problem in coronary angiography. Usually
    one of these three physical media is used: cine film, videotape, or
    digital storage. The properties of these different archive tapes are
    analyzed by comparing their benefits for clinical practice. The most
    important criterion for clinical diagnosis is the image quality.
    Extensive studies have been performed to compare images from digital
    storage, digitized cine film, VHS videotape, and worn videotape. By
    using special X-ray phantoms, various image properties were measured.
    The results show that digital images have the best quality in terms of
    noise, sharpness, and pointspreading. Cine film has advantages in
    spatial resolution, but disadvantages in contrast. The video images,
    especially those from worn tape, have a dramatic loss of spatial
    resolution and sharpness. Digital technology offers several progressions
    like online enhancement, fast accessibility, quantitative coronary
    analysis, data integration, communication, and telemedicine
