Abstract :
Computerized tomography is nowadays largely diffused; however, the high radiation dose delivered to the patient tissue and the elevated cost of the tomographic apparatus are often not justified for the applications of the clinical dental field (e.g. implantology). Here we propose to use a traditional ortopantomograph, which is equipped with a cheap, linear sensor, to acquire a set of projections from a limited angle of view; from these projections, the volume of interest is reconstructed through tomosynthesis and successively deblurred. The encouraging results illustrated here demonstrate the feasibility of the approach, which may open the door to a superior class of multifunction ortopantomographs.
