The measurement of the intima-media thickness (IMT) of the carotid artery walls with B-mode ultrasound imaging is a technique which is non invasive, safe and well tolerated by patients. Moreover, population studies conducted on men and women with different risk factors for atherosclerosis, have shown that a strong correlation exists between the measure of the IMT and the classical risk factors. For these reasons, the IMT measurement has emerged as one of the most attractive techniques for the evaluation of cardiovascular risk in recent years. IMT is defined as the distance between the leading edge of the lumen-intima interface and the leading edge of the media-adventitia interface. To locate such edges, a manual approach is usually used. However, such a method is time consuming and rather unreliable since tracing results may depend on the experience, training and subjective judgment of the operator, thus involving a great inter- and intra-operator variability. Moreover, such an approach can not be applied to large databases of images. Many efforts have been made in developing new automatic procedures to make this technique less operator dependent. In the present invention, an automatic technique for the IMT measurement, which exploits a new edge detector (i.e. the first absolute central moment) and a pattern recognition approach, is developed. The present invention can be used to measure intima-media thickness of the carotid artery walls with B-mode ultrasound imaging. (literal)
