The impact of vendor-specific ultrasound beam-forming and processing techniques on the visualization of in-vitro experimental “scar”: implications for myocardial scar imaging using 2D and 3D echocardiography.

Myocardial scar appears brighter compared to normal myocardium in echocardiography due to differences in tissue characteristics. We tested how different ultrasound pulse characteristics impact on the brightness contrast (i.e. contrast ratio, CR) between tissues of different acoustic properties, as well as the accuracy of assessing tissue volume.
