Abstract
An Angiographic X-ray imaging system includes a detector for automatically detecting a transition between different phases of contrast enhanced blood flow in vessels of a portion of patient anatomy, in response to pixel luminance content of at least one image of a sequence of acquired images of the portion of patient anatomy. An X-ray imaging device uses the detector and information associating different sets of X-ray imaging device settings with corresponding different phases of contrast enhanced blood flow in vessels for automatically sequentially acquiring images in different phases using different imaging settings, in response to detection of transitions between different phases.
