摘要: Evaluation of cavitation in vivo is often based on recordings high-pass filtered random high-frequency pressure fluctuations. We hypothesized that signal components are more appropriately assessed by a new method for extraction the signals. investigated three different valve types and found high correlation between two methods~r 2 :0.880620.9887!. The showed could be extracted without priori knowledge needed setting filter cut off frequency, nor did it introduce bandwidth limitation signal. @DOI: 10.1115/1.1613297#
