Abstract

We introduce a framework to simulate intravascular ultrasound (IVUS) from histological sections. These sections were previously acquired along with real IVUS radiofrequency signals using single-element 40MHz transducer. After labeling and registering the section to the corresponding IVUS image, a virtual phantom was created, incorporating nuclei scatterer patterns. A finite differences simulation of the acoustic signal was performed, resulting in backscattered radiofrequency signals. These were used to process a B-mode image, which in turn was compared to the real IVUS image of the same section. A high image quality with a very promising correlation to the original IVUS images was achieved.

Clinical Relevance

Over 8 millions people die from strokes or cardiac diseases each year. Over half of these are caused by atherosclerosis. Intravascular Ultrasound (IVUS) is an excellent tool for diagnosing atherosclerosis, as stenosis and calcified tissues are clearly visible. However critical structures as vulnerable plaques are hard to identify with conventional means. Simulating IVUS and developing acoustic models for relevant tissue types will help in a better understanding of the physical processes within tissues and their interaction with acoustic waves. These will eventually lead to improved tissue characterization methods.
