Intravascular Ultrasound Imaging with Virtual Source Synthetic Aperture (VSSA) focusing and Coherence Factor Weighting (CFW).

Intravascular ultrasound (IVUS) has been frequently used for coronary artery imaging clinically. More importantly, IVUS is the fundamental image modality for most advanced multimodality intravascular imaging techniques, since it provides a more comprehensive picture of vessel anatomy on which other imaging data can be superimposed. However, image quality in the deeper region is poor because of the...
