    摘要: A system (900), method (100, 200) and apparatus (600, 700, 800) are provided for analyzing a blood flow in a vascular system from a dynamic diagnostic observation sequence (101) to determine blood flow parameters (112) for further determination of filters, replay speed and finally visualization of the replayed original and filtered sequences. A first embodiment (100) extracts features of the observation and uses these features to select an appropriate model from a database of pre-determined models of vascular system of interest which have associated parameters. These parameters are varied to create an instance of the model that best matches the original observation. A second embodiment (200) visualizes a replay of the original observation (101) and the observation (101′) predicted by the model to highlight differences therebetween. A third embodiment (800) provides filtering and control of the replay speed.
