摘要： A method and apparatus for imaging including reconstruction of an image of an object from a set of projections acquired for different positions of an acquisition apparatus around the object to be imaged and in which a projection source is situated at a finite distance relative to the acquisition apparatus. The method includes undertaking a set of rectifications of projections acquired for different positions of the acquisition apparatus, rectifications comprising transforming the data of the projection acquired projection into projection data on a virtual rectification support placed in a preset orientation in concordance with a set of reconstruction calculation points distributed over the image to be reconstructed.

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 system for navigating an image-guided object through an imaged subject supported on table in relation to an image acquired by an image detector is provided. The system includes a first tracking element attached to the patient, and a second tracking element attached at the table.

摘要： An image processing method for interventional imaging in which a region of interest of a patient is viewed. The method comprises acquiring a succession of images of a region of interest of the patient. The method also comprises detecting and tracking, on the successive images, at least one surgical instrument introduced inside the region of interest of the patient, in order to isolate said instrument therein; and comparing two successive images on which the surgical instrument has been isolated in order to identify at least one common shape therein. The method further comprises estimating the displacement of said common shape between both of these successive images; and re-alignment processing of the different successive images depending on the thereby determined estimations of displacements, these displacement estimations being considered as corresponding to the displacement caused by the physiological movement of the patient with the exception of any other movement.

摘要： A method using an imaging device to define an acquisition geometry for 2D images of an observation region, a region for which there exists a 3D representation. 2D views of the 3D representation can be determined following the acquisition geometry of the imaging device for a plurality of viewing points, so that each acquired 2D image can be superimposed with any of this plurality of views. As a variant, in the 3D representation two views are determined corresponding to the viewing point at which the eye is positioned at the formation plane of the acquired image (front view and corresponds to the 2D image) and to the viewing point at which the eye is positioned at the focal point of the projective geometry (back view which is opposite to the viewing point of the 2D image). These two views allow the generation of two images for superimposition over the acquired image, defining superimposition of the acquired image with a front view of the 3D representation of the observation region and superimposition of the acquired image with a back view of the 3D representation of the observation region.
