ABSTRACT:
An angiography system is described for acquiring both cine-film and T.V. or digital video images for at least two planes, including at a rate of 30 fps per plane. In one embodiment of the present invention, a single-channel digital acquisition system comprises a frontal x-ray source with corresponding frontal T.V. and frontal cine-film cameras, a lateral x-ray source with corresponding lateral T.V. and cine-film cameras, and circuitry for eliminating motion artifacts.
