This study introduces an effective algorithm to suppress low-frequency Doppler signals in color flow imaging. This method improves velocity resolution for better visualization of time-dependent phenomena.

Area of Science:

  • Medical Imaging
  • Ultrasound Technology
  • Signal Processing

Background:

  • Color flow imaging requires high flow map rates and good velocity resolution for accurate assessment of time-dependent phenomena.
  • Velocity resolution is influenced by signal segment length and high-pass filter settling times, which can introduce artifacts.

Purpose of the Study:

  • To develop and evaluate an algorithm for effective suppression of low-frequency Doppler signals.
  • To ensure all data points contribute equally to the computed average Doppler frequency.

Main Methods:

  • An algorithm was designed to suppress low-frequency Doppler signals efficiently.
  • The algorithm was tested using computer-generated Doppler signals to analyze time and frequency behavior.
