Real-time 3D ultrasound (4D US) is a non-invasive imaging technique that provides information on human aortic wall deformation for tissue regions with a size of less than 20 square mm. The Research Laboratory Personalized Biomedical Engineering has proposed these data as biomarkers for the evaluation of abdominal aortic aneurysm rupture risk and as basis for the in vivo identification of the individual elastic properties of the aorta.
At the 53. Annual Conference of the German Society for Biomedical Engineering, Frankfurt/M., 25./26.09.2019, we will present a validation study on uncertainty and reproducibility of 4D US measurements (Session F3: FT Image Processing). The study was conducted in cooperation with the Department of Vascular and Endovascular Surgery of the Goethe-University Hospital. The figure gives the comparison of 4D US (red) and optical (blue) measurements: the diameter change of a pressurized porcine aorta is plotted against time (Source: Research Lab PBE).
