Investigating the Influence of the Physiological Environment on Quantitative Contrast-enhanced Ultrasound Imaging

Conclusion It has been re-established that as temperature increases from room temperature to body temperature, considerable signal is lost and attenuation and backscatter increase with temperature. Blood cells surrounding the bubbles do alter the attenuation; however, they do not have any effect on the backscatter by the bubbles. This result is different from previous studies, and therefore, more work must be done to validate these results in a more sophisticated experimental setup. Confinement of bubbles inside small vessels affects both attenuation and backscatter. Hence, while designing experiments, care must be taken about choosing the vessels in the body through which the bubble will travel and the parameters must be measured accordingly.
