A method that simulates angiographic procedure is presented. The intended purpose is to provide simulated angiograms so that mechanisms for reconstruction the vasculature can be rigorously tested. Three elements are modelled; the vasculature and blood flow, the x-ray device, and the contrast agent and its injection. These modelling elements are specified by parameters supplied by the user, leading to a versatile simulation that captures many of the salient features of angiography. The simulation yields sets of time sequenced angiograms - an animation. Each set depicts flow of agent through the vasculature from one point of view. Such sets may be acquired either simultaneously, or through independent injection events. Results in the form of simulated angiograms are presented.
