Abstract
A common application of X-ray fluoroscopy is in monitoring the location of a catheter inside a body. Such catheters may be used for balloon angioplasty, laser ablation, or like procedures that are now often used in place of traditional invasive surgery. Reliable and fast determination of the tip location from the fluoro images using the digital image processing technique is required. The present invention relates to a method for tracking a catheter probe or similar object during a fluoroscopic procedure as may be utilized, for example, in conjunction with apparatus and methods that confine full X-ray dosage to a central area, compensating for the reduced X-ray dosage in the peripheral areas by computer imaging enhancement.
