Segmentation of Prefrontal Lobe Based on Improved Clustering Algorithm in Patients with Diabetes

Figure 1

Segmentation of the prefrontal lobe on the transverse plane. (a–c) Three typical transverse plane between the upper end of the frontal lobe to the lateral ventricle. Find the anterior central sulcus, along the deepest part of the sulcus, draw a straight line perpendicular to the longitudinal fissure of the brain. (d) Typical plane through the lateral ventricle. Draw along the anterior central sulcus to the front point of the lateral ventricle; then, draw a straight line to connect with the deepest point of the longitudinal fissure. (e) Typical plane through the lateral sulcus. Draw a line along the front of the lateral sulcus to the front point of the lateral ventricle. (f) Typical plane with the disappeared lateral ventricle. The lateral fissure was the posterior boundary of the prefrontal lobe and delineated along the boundary of the frontal lobe.
