1. A method of utilizing bolus propagation and control for contrast enhancement comprising:

  • measuring with an imaging device a position of a bolus moving along a path in a biological structure;

    predicting a future position of the bolus using a simplified target model;

    comparing the predicted future position of the bolus with the measured position of the bolus;

    determining a control action to eliminate a discrepancy, if any, between the predicted position of the bolus and the measured position of the bolus; and

    adaptively adjusting the relative position of the imaging device and the biological structure according to the control action to chase the motion of the bolus.
