Method for Aortic Wall Strain Measurement With Three-Dimensional Ultrasound Speckle Tracking and Fitted Finite Element Analysis

Three-dimensional ultrasound speckle tracking enables the analysis of spatially highly resolved strain fields of the aortic wall and offers the potential to detect local aortic wall motion deformations and abnormalities. These data allow the definition of new indices by which the different biomechanical properties of healthy aortas and aortic aneurysms can be characterized.
