摘要： A system and method of calibrating an imaging system, in which intrinsic parameters relating to the various types of image which can be taken are calibrated in predetermined angular positions of an emitter of radiation, and of a receiver of the radiation. The intrinsic parameters are estimated using a two-dimensional phantom in order to establish a distortion field for a particular angulation, the distortion field for any angulation being calculated by polynomial interpolation of the distortion fields, each established for a control point, a control point being defined by a particular angulation for each axis of rotation of the imaging system, having to be subject to calibration.

摘要： A method and apparatus for determining acquisition geometry of an imaging system from a set of calibration matrices for an arbitrary position of the system, a projection matrix makes a point in a 2D image correspond to a point of an object in a space. This matrix is produced for any unspecified position of the system from knowledge of a limited number of pre-computed calibration matrices. For instance, a projection matrix may be computed by interpolating coefficients of calibration matrices and/or applying a transformation with a rigid model defined comprehensively or locally to a particular calibration matrix.

摘要： A method of cardiac radiological examination for coronarography comprises the steps of: a) introducing contrast medium simultaneously in the left coronary artery and in the right coronary artery from the aortic root and, in parallel, b) acquiring a sequence of dynamic images of the propagation of the contrast medium in the left and right coronary arteries with a displacement of the image plane, during the acquisition of said images, along a determined trajectory (E28). The contrast medium can be introduced in a cyclic manner during the acquisition of dynamic images, each cycle of introduction corresponding to a phase of closure of the aortic valve in the cardiac rhythm. 3D and 4D images with optimal efficiency can be obtained in the use of contrast medium. An injection device for producing the above cycles is synchronized with the introduction of the contrast medium.

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
