Abstract:
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, wherein the simplified target model is a non-parametric model and wherein predicting the future position of the bolus comprises estimating the future position by {circumflex over (p)} 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.
