摘要
A method is proposed to simulate intravascular ultrasound （IVUS） images of athero-sclerotic plaques. To accomplish the simulation of static IVUS plaque images, the ringdown and guidewire artifacts are introduced into the polar image-formation model （PIFM）, and the fibrous, lipid and calcific contents are synthesized in plaques respectively. The simulation of sequential IVUS images can be achieved by utilizing characteristics of the pulsatile artery. The results on static images demonstrate that it outperforms the PIFM method by 56.9% in terms of the correlation coefficient （CC）, and 24.3% in terms of the mutual information （MI）. The results on sequential images demonstrate that it outperforms the PIFM method by 51.0% in terms of CC, and 10.3% in terms of MI.
