Abstract:
1. A circuit for providing an image representation supporting accurate guidance of an intervention device in a vessel intervention procedure in a region of interest of a patient, in which region a position of an object of interest is depending on at least a first source of motion, said circuit being configured for performing a plurality of acts, from among said plurality there being the acts of: (i) acquiring a first sequence of images of said region of interest with the intervention device inserted into said region of interest during a time frame without a first motion of the patient; (ii) detecting a first motion sequence of a periodic motion of the intervention device during a cycle of second motion by analyzing motion of the intervention device in the first sequence of acquired images; (iii) creating a motion model representative of motion, of the intervention device, that is solely induced by the second motion; (iv) determining an operator (H) defining a relationship between said first motion sequence and the second motion; (v) acquiring live images of said region of interest with the intervention device inserted into said region of interest; (vi) subtracting said solely induced motion using the operator (H) and determining the motion of the intervention device induced by the first motion of the patient; and (vii) registering of a previously acquired image of an object of interest based on the first motion.
