Section Plane Effects on Morphometric Values of Microcomputed Tomography

Figure 2

Example images of HM and morphometry of MCT. From top to bottom, the first row: HM image; the second row: the selected MCT image that is the closest possible to the HM (the original MCT); the third row: + 4 offset image from the original MCT; the fourth row: - 4 offset image from the original MCT; + 10 degree rotation image from the original MCT; - 10 degree rotation image from the original MCT. Left column: raw images; center column: segmented images into 3 regions, i.e., bone area, graft area and noncalcified area; right column: color-filled segmented images. The two different colors are used for this purpose at the images of middle and right column in the same row for discrimination. For example, at the image of middle column and first row of histomorphometric (HM) images, the green line demarcates the graft area whereas the blue line does the bone area. Then, the demarcated areas are filled with the same colors at the images of the right column and first row. Likewise, in the second row, yellow color is used for graft area and skyblue color is used for bone area. The differences occurring according to the section plane are easily identified.
