Area of Science:

  • Medical Imaging
  • Biomedical Engineering
  • Ultrasound Technology

Background:

  • Accurate estimation of slow blood flow is challenging with conventional ultrasound.
  • Existing methods may struggle with angle dependency and low velocities.

Purpose of the Study:

  • To develop and validate a high-frequency ultrasound technique for precise slow blood flow quantification.
  • To combine Speckle Flow Imaging (SFI) and block matching for comprehensive velocity vector estimation.

Main Methods:

  • Speckle Flow Imaging (SFI) analyzes temporal speckle pattern changes for total velocity.
  • Block matching estimates in-plane velocity components.
  • Integration of SFI and block matching for 3D velocity field evaluation.

Main Results:

  • Good agreement between SFI and a statistical model on calibrated flow sequences.
  • Angle-independent flow quantification achieved for perpendicular flow.
  • Accurate in-plane velocity estimation by Speckle Tracking for low orthogonal velocities (<1mm/s).

Conclusions:

  • The combined technique enables accurate 3D blood flow velocity field evaluation.
  • Allows for precise quantification of volumetric blood flow.
  • Offers an angle-independent method for slow blood flow measurement.
