摘要: Objective: The purpose of this study was to determine a conversion coefficient for Hounsfield Units (HU) material density (g cm−3) obtained from cone-beam computed tomography (CBCT-NewTom QR-DVT 9000) data. Methods: Six cylindrical models materials with different densities were made and scanned using the NewTom 9000 Volume Scanner. The raw data converted into DICOM format analysed Merge eFilm AMIRA HU areas models. Results: There no significant difference (P=0.846) between given by each piece software. A linear regression performed density, ρ (g cm−3), as dependent variable in terms (H). equation ρ=0.002H−0.381 an R2 value 0.986. standard error estimation is 27.104 HU case 0.064 g cm−3 density. Conclusion: CBCT provides effective option determination expressed ...
