摘要： A medical imaging device and method having a display screen, a processor for processing image data in order to display the data in the form of a 3D model, and a user interface. The processor acquires at least two points positioned in the 3D model via the user interface; deduces the positioning of an axis defined by the two points in the 3D model, and reorients the 3D model in such a manner that the axis as indicated in this way is to be found in a predefined orientation relative to the plane of the display screen.

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.
