摘要： The process comprises a calibration of the apparatus, in which a virtual volume surrounding the object is generated and broken down into voxels, an acquisition of the set of numbered projected two-dimensional images, and a reconstruction of the three-dimensional image from the projected acquired two-dimensional images, and from an iterative algebraic image reconstruction algorithm. A first iteration of the algorithm is performed with a predetermined initial image resolution so as to obtain, at the end of this first iteration, first density values for the voxels of the volume, at least one part of the voxels of the virtual volume is subdivided into several sets, respectively, corresponding to different image resolutions that are multiples or sub-multiples of the initial resolution, and during each subsequent iteration of the algorithm, the algorithm is successively aplied to each of the sets of voxels.

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
