    <p>Morphometric indices corresponding to the trabecular bone microarchitecture and cortical bone morphology in the mandibles of the control and ovariectomized groups.</p

    <p>The linear fitting function is <i>y</i> = 0.0052<i>x</i>+0.051 (<i>R</i><sup>2</sup> = 0.993), where <i>x</i> is the absorbed dose and <i>y</i> is the homogeneity.</p

    Linearity maps of entropy and homogeneity at 500× and 3500× magnifications.

    <p>The <i>x</i> and <i>y</i> axes are the distance (<i>d</i>) and the exclusion number (<i>e</i>), respectively, and the pixel value in the matrix represents the <i>R</i><sup>2</sup> value of the corresponding DRC. Homogeneity was more sensitive to <i>d</i> and <i>e</i> than entropy at both magnification levels.</p

    Sixteen sub-micrographs divided from the original 500× magnified SEM image irradiated with 20 Gy.

    <p>The homogeneity is attached in the lower-left corner of each sub-image. Impurities in the gel g007matrix caused variations in the texture analysis results.</p

    <p>The <i>x</i> and <i>y</i> axes are the distance (<i>d</i>) and exclusion number (<i>e</i>), respectively, and the pixel value in the matrix represents the normalized absolute value of the slope of the corresponding DRC. Entropy had relatively stable results than homogeneity at both magnifications.</p
