The graph of the decision function for classification (quadratic) of healthy subjects (red) from patients (green) depending on the features w (1), w (2) and w(3) for the images of the: a) left transverse section of the thyroid LO, b) right transverse section of the thyroid RO, c) left and right transverse sections of the thyroid LRO, d) left longitudinal section of the thyroid LD, e) right longitudinal section of the thyroid RD, f) left and right longitudinal sections of the thyroid RLD, g) left and right transverse and longitudinal sections of the thyroid LROD. The decision function was selected automatically and the classification gave the following results: graph a) specificity at 0.9 and sensitivity at 0.62, graph b) specificity at 0.87 and sensitivity at 0.74, graph c) specificity at 0.89 and sensitivity at 0.64, graph d) specificity was at 0.89 and sensitivity at 0.77, graph e) specificity was at 0.92 and sensitivity at 0.62, graph f) specificity of 0.89 and sensitivity of 0.7 and graph g) specificity is at 0.89 and sensitivity at 0.65.
