Brilliance 40 slice ct

Following a post-surgical period, conventional radiographic examination and computer tomography (CT) of the mandible body after euthanasia were carried out to assess the regeneration of the cortical bone tissue.
The radiographs in the lateral view of the porcine head were obtained using an X-ray machine (Philips Digital Diagnost, Delft, The Netherlands).
CT scans of the head were obtained with a computed tomograph (Philips Brilliance 40-slice CT, the Netherlands) in the axial and sagittal plane. They were used to evaluate neoformation of the bone tissue on the mandible.

X-ray analysis was done employing X-ray equipment (Philips Digital Diagnost, The Netherlands) at the exposure settings of 55–60 kV and 1.8–4.9 mAs and the pixel size of 0.133 mm. CT scans were obtained using a CT (Philips Brilliance 40-slice CT, Delft, The Netherlands) with the following scanning parameters: 120 kV, 250 mA, 300 mAs, pixel size 0.283 mm, thickness of slices 2 mm. We evaluated the presence of nonresorbed and nondegraded biomaterial, pathological and inflammatory changes, and the density of the newly formed bone tissue compared to the surrounding physiological bone. The bone density was evaluated using Hounsfield units (HU).
