Correspondence: Quantitative analysis of ultrasound contrast agent postexcitation collapse

摘要

An empirically based peak-detection technique is described for statistically analyzing single ultrasound contrast agent collapses. It is shown that microbubbles with postexcitation collapse initially exhibit a stronger principal response on average than those without postexcitation, and that lower insonifying frequencies lead to postexcitation signals which have greater separation from their principal response and persist through more rebounds.
