How Analyze was Used
“3D images of the implant specimens and bone growth were constructed… Briefly, following scanning, the images were segmented using Analyze software version 12.0 (AnalyzeDirect, Overland Park, KS, USA) and filtered to reduce imaging noise. Then, the dataset was manually reoriented using Analyze software to visualize standard coronal, sagittal, and horizontal planes through the implants. The images were reformatted to cubic volume (3D) with a resliced 30-μm image thickness of the surface area on the implant outer surface for the cross-sectional and longitudinal axes. The segmentations of implant and bone-growth images were also performed on Analyze software. As such, 3D rendering of the implants and bone growth was completed. To determine the bone volume on the implant surface in 30-μm thicknesses, the original scanned images were rotated by 10 degrees and the segmentations and 3D rendering were repeated. These 18 repetitions produced the overall 3D bone growth image on the implant surface in 30-μm thicknesses. The 3D BIC area was the bone formation area on the cylindrical surface of the implant. Assuming that the volume in 30-μm thicknesses was homogeneously filled with bone, the 3D BIC area was determined by dividing the bone volume by the thickness (30 μm).”
