Numerical simulation of intravascular ultrasound images based on patient-specific computed tomography.

Intravascular ultrasound (IVUS) provides detailed imaging of the artery circumference. Over the past years, the interest in artificial intelligence for interpretation and automatic analysis of IVUS images has grown. Development of such algorithms typically requires considerable amounts of annotated data.

Geometry and local wall thickness of abdominal aortic aneurysms using intravascular ultrasound.

Currently, abdominal aortic aneurysms (AAAs) are treated based on the diameter of the aorta, however, a more robust patient-specific marker is needed. The mean thickness of the wall is a potential indicator for AAA rupture risk, which varies significantly within and between patients. So far, regional thickness has not been used in previous rupture risk analysis studies, since it is challenging to measure in CT, MRI, and non-invasive ultrasound (US).
