An Improved Approach for Accurate and Efficient Measurement of Common Carotid Artery Intima-Media Thickness in Ultrasound Images

Figure 9

Examples of the extracted ROI and the final boundaries. The first five examples illustrate the correctly detected IMT and the last one shows the case of failed detection. In (c) and (e), the intima layer is incomplete. In (b) and (c), the adventitia layer is destroyed by noises or artifacts. In (f), the intima layer is completely disappeared and the IMT measurement is failed.
