title: Evaluation of quality of reformatted images from two cone-beam computed tomographic systems.
abstract: OBJECTIVE
  The aim of the study was to compare image quality of two different systems based on cone-beam computed tomography (CBCT).
  
  
  METHODS
  Primary and secondary reconstructions were performed from data sets of the Siremobil Iso-C(3D) (Siemens Medical Solutions, Erlangen, Germany) and the NewTom 9000 (NIM s.r.l., Verona, Italy) using a dried human skull. Using defined anatomical structures, image quality was analysed by 10 examiners using a ranking scale.
  
  
  RESULTS
  Regarding image quality there was no statistically significant difference between the two systems compared.
  
  
  CONCLUSIONS
  The preliminary results show, that imaging of the facial skeleton using the Siremobil Iso-C(3D) can be performed with a quality comparable to the NewTom 9000.
