Method for the reconstruction of a panoramic image of an object, and a computed tomography scanner implementing said method

摘要

In a computed tomography scanner, the panoramic image of an object to be analysed is reconstructed by: acquiring volumetric tomographic data of the object; extracting, from the volumetric tomographic data, tomographic data corresponding to at least three sections (17a-17c) of the object identified by respective mutually parallel planes; determining, on each section (17a-17c) extracted, a respective trajectory (20a-20c) that a profile of the object follows in an area corresponding to said section (17a-17c); determining a first surface (S) transverse to said planes such as to comprise the trajectories (20a-20c); and generating the panoramic image on the basis of a part of the volumetric tomographic data identified as a function of said surface (S).
