摘要： 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

摘要： A method for the processing of images in interventional radioscopy to produce a sequence of de-noised images in which elongated objects of guiding instrumentation equipment are preserved and enhanced. The method of the invention uses a tool for indicating the confidence to be placed in a given pixel as regards its belonging to a piece of guidance equipment. This tool is used to create a combination algorithm capable of re-injecting the pixels having a low contrast-to-noise ratio into the de-noised image. This combination algorithm enables the enhancement solely of the pixels of the guidance equipment with a high confidence value so as not to produce artifacts with the enhancement of false positives.

The process includes: determining a predicted image of the object at the instant t as a function of the images of the object acquired at the instants t-i, i being a positive whole number greater than or equal to 1, and moving of each of the layers constituting the image acquired at the instant t, the number of layers being previously fixed and the moving of each of the layers being previously determined; and generating a visualized image corresponding to a weighted sum of the predicted image and the image of the object acquired at the instant t, so as to attenuate the noise of the image of the object acquired at the instant t.

摘要： A method and apparatus for determining a magnification factor in a radiography device of the type comprising an X-ray source and means for acquiring images placed facing the source, the source and the means for acquiring images being mounted so as to rotate about at least one axis with respect to a support on which an object to be X-rayed is intended to be positioned. The method and the apparatus implementing the method comprises: acquiring at least two images corresponding to two different angular positions of the source and of the recording means with respect to the support; identifying on these images projections of at least one point of the X-rayed object; and determining the magnification factor of at least one of the images, first, as a function of the angular displacement of the source and of the recording means between the acquisitions of the images in question and, secondly, as a function of the positions on these images of the identified projections.
