Method and apparatus to increase the field of view in a cone-beam computerized tomography acquisition

摘要

Method and apparatus for increasing the Field Of View dimensions in a cone-beam computerized tomography acquisition, comprising the following steps:
A. Selecting an acquisition protocol;
B. Positioning a patient;
C. Performing a first subacquisition step of a first anatomic area of at least two partially overlapping anatomic areas;
D. Repositioning the apparatus for the next subacquisition step;
E. Performing the at least one next subacquisition step of the at least further anatomic area;
F. Generating the volumetric images relating to the subvolumes;
G. Reconstructing a single global volumetric image
in which the reconstruction occurs through techniques of image registration (stitching) and blending.
