Summary
Cinefilm will gradually be replaced by some digital media for the archiving of angiographic images. We constructed a network system of coronary angiographic movies with an image server, two acquisition systems(Catheter Laboratory), and eight image viewers. We examined the image transmission speed of each modality, and that of the latest one was 7.2 frames per second. The review speed from network image to viewer is less than half the acquisition rate, but the review speed is not reduced by multiple, simultaneous requests to the server for the same data.
