A novel method accurately determines the Doppler probe angle using standard pulsed Doppler ultrasound. This technique precisely calculates the vessel-skin angle, crucial for accurate blood flow measurements.

Area of Science:

  • Medical Imaging
  • Ultrasound Technology
  • Biomedical Engineering

Background:

  • Accurate Doppler probe angle is essential for reliable blood flow velocity measurements.
  • Existing methods for angle determination can be complex or inaccurate.
  • Standard pulsed Doppler systems require precise angle estimation for clinical use.

Purpose of the Study:

  • To introduce a new, accurate method for determining the Doppler probe angle.
  • To enable precise vessel-skin angle calculation using standard pulsed Doppler equipment.
  • To improve the accuracy of Doppler ultrasound measurements in clinical settings.

Main Methods:

  • The method utilizes the transit times of ultrasound waves from multiple probe positions.
  • It measures the distance between probe positions and the probe-skin angle.
