Abstract: Method for correcting an acquired medical image of a patient showing a representation of an internal body structure, the acquired image having been acquired in a medical imager having a radiation source and a radiation detector spaced from one another along an image-taking direction, and between which the patient is disposed. One obtains, from the acquired image, a corrected image taking into account a position of the internal body structure along the image-taking direction.

Abstract: A method for measuring geometric quantities intrinsic to an anatomical system of a patient, based on two stereoscopic images. Registration data are received on each of the two stereoscopic images. By using geometric calibration information, a three-dimensional geometric primitive is determined defined by at least a portion of the received registration data. Based on the three-dimensional geometric primitive, a value of geometric quantity intrinsic to the anatomical system is computed.

Abstract: A radiographic imaging method for three-dimensional reconstruction in which the three-dimensional shape of a model representing an object is calculated from a geometrical model of the object that is known a priori, and obtained from a confinement volume of the object estimated from a geometrical pattern visible in two images and from knowledge of the positions of the sources. A geometrical model is used that comprises information making it possible using an estimator for the object to establish a geometrical characteristic for the model representing the object.
