Methods for measuring times-of-flight of ultrasound echo signals

Abstract

Disclosed is a method for measuring time-of-flight of an ultrasound echo signal, and relate to the field of measurement technology. The method comprising: capturing an echo signal; obtaining a reconstructed echo signal by performing denoising and reconstruction on the echo signal using an empirical wavelet transform; obtaining a preset reference echo peak value and a reconstructed echo peak value, and determining an echo characteristic peak of the reconstructed echo signal using a preset characteristic peak positioning algorithm; obtaining echo characteristic point of the echo signal; and measuring the time-of-flight of the echo signal based on the echo characteristic point using a preset measurement algorithm. Using the provided method, the time-of-flight of the ultrasound echo signal can be obtained more accurately through simple calculations.
