摘要: Background and aims. Cone-beam computed tomography (CBCT) is an imaging system which has many advantages over (CT). In CT scan, Hounsfield Unit (HU) proportional to the degree of x-ray attenuation by tissue. CBCT, shown gray scale (voxel value). The aim present study was investigate relationship between in CBCT) scan. Materials methods. this descriptive study, head a sheep scanned with 3 CBCT one medical scanner. Gray scales HUs were detected on images. Reconstructed data analyzed HUs. Results. A strong correlation scan determined. Conclusion. Considering fact that criteria measurement bone density before implant treatments, it recommended because lower dose cost compared
