Abstract
A periodically moving object, e.g., the heart, is X-rayed in response to periodic pulses generated at instances in the period at which the object is anticipated to be in a given position. Stochastic movements shift the position of the object at those instances such that image artifacts may result. A prediction methodology is utilized to predict when the object has moved stochastically and therefore will be out of position at the forthcoming pulse. That forthcoming pulse is then suppressed to preclude imaging the object out of position. Kalman filtering is utilized in the prediction methodology.
