Multi-Domain TLM Model for Intravascular Ultrasound

Developed in this paper is the set up of a spatiotemporal (multi-domain) numerical model for intravascular ultrasound (IVUS). The transmission line matrix method (TLM) is used to mimic the propagation of the sound wave through the circular cross-section of an artery. Different propagation scenarios (healthy and abnormal arteries) are illustrated in this work showing how this model captures the behavior of these waves. The model is evaluated by means of regular TLM models established in the literature.Copyright © 2009 by ASME
