1. A method of increasing Field Of View (FOV) dimensions in an apparatus for cone-beam computerized tomography (CBCT) acquisition, the method comprising: A. selecting an image data acquisition protocol comprising a sequence of sub acquisition steps, each sub acquisition step including acquiring raw image data of a subvolume covering one of a first or a second adjacent to and partially overlapping anatomic areas; B. positioning a patient to be imaged; C. performing a first subacquisition step of the first anatomic area; D. repositioning the apparatus for a second subacquisition step of said sequence of sub acquisition steps; E. performing the second subacquisition step of the second anatomic area, said second anatomic area being adjacent to and partially overlapping said first anatomic area; F. generating volumetric images of first and second subvolumes respectively covering the first and the second anatomic areas starting from the corresponding raw image data acquired during each of the first and the second subacquisition steps; and G. reconstructing a single global volumetric image from said volumetric images of the first and the second subvolumes, wherein the step of reconstructing said single global volumetric image is performed through an image registration process that includes stitching and blending of at least part of said volumetric images of the first and the second subvolumes.
