1. A system, comprising: an interventional apparatus including a interventional instrument configured to perform an image-guided interventional procedure for a patient, the interventional apparatus including a position detector that detects a position of the interventional instrument within a region of the patient at which the image-guided interventional procedure from outside of the region of interest is performed and generates a movement signal indicative of the detected position; and an imaging scanner including a controller that activates the imaging scanner to scan the region of interest and the interventional instrument therein for one or more data acquisition cycles based on the movement signal.
