NONINVASIVE SYSTEMS FOR AORTIC ANEURYSM EVALUATION

摘要

Hardware and software methodology are described for non-invasive approaches to aortic aneurysm evaluation using ultrasound, microwave, and/or other radiofrequency (RF) techniques. Embodiments can be used to diagnose AAA and other aortic aneurysm conditions by non-invasive measurement and computation of displacement-based wave intensity (DWI) and/or displacement-based reflected wave intensity (DRWI) along the aorta and by comparison of the results to baseline data for a given patent or a population sample catalogue. Deviation of DWI and/or DRWI from a normal condition can be used to assess the severity of the AAA or other aortic aneurysm and any associated rupture risk.
