Abstract
A method for processing images in interventional radioscopy for detecting guiding instrumentation equipment. The method of the invention enables objects of longilinear or very curved shapes to be detected within the radioscopic image having very low contrast to noise ratios. In one embodiment, an algorithm enables the measured contrast to noise ratio of long or curved structures in the image to be considerably improved. To do this, an embodiment of the invention uses oriented, separable, recursive and rapid steerable detection filters. Said detection filters have a low calculation cost, even for long filters having several orientations.
