High frequency (>20MHz) ultrasound imaging has made it possible to delineate small structures with fine spatial resolution. Previously, a high frequency high frame rate imaging system had been developed for small animal cardiac imaging [2, 5]. This paper presents further development of a programmable, low-cost, real-time high frequency ultrasound imaging board based on high-speed FPGA. Utilization...
Zebrafish can fully regenerate their myocardium after up to 20% ventricular resection within 2 months without evidence of scar tissues. The extraordinary regenerative abilities provide a significant model system to study the activation of the regenerative potential of human heart tissue. In order to characterize cardiac functions of zebrafish during heart regeneration, we used high-frame-rate high-frequency...
Understanding heart regeneration in a vertebrate model system is a highly relevant public health concern. Coronary heart disease is among the leading causes of disability and mortality worldwide. Injured human hearts caused by myocardial infarction (MI) results in decreased cardiac performance and eventually the development of heart failure. In contrast to mammals, zebrafish fully regenerate myocardium...
