ABSTRACT:
An apparatus for reducing accumulated X-ray dosage during a fluoroscopic examination adaptively varies the time between exposures, X-ray beam strength, and beam extent and aim point during the course of the procedure in real-time. A temporal sequence image analyzer identifies a catheter in the fluoroscopic image and forms a prediction of its movement based on a time-series of fluoroscopic images. This prediction model is used to modulate the X-ray beam to produce a much smaller fluoroscopic image including only the area in the vicinity of the catheter tip. An output image synthesizer produces a useful output image by combining these stored sub-images.
