Evaluation of quality of reformatted images from two cone-beam computed tomographic systems.

摘要

PURPOSE: The aim of the study was to compare image quality of two different systems based on cone-beam computed tomography (CBCT). STUDY DESIGN: 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. CONCLUSION: 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.
