January 1, 1997Ultrasonic Imaging

The SVD filter demonstrated good performance, particularly with a large temporal window (approximately 100 RF signals) for low blood flow velocities, compared to the SLR filter.

Overview

SVD filtering may aid low-velocity Doppler imaging; leaves open clinical validation and efficiency trade-offs.

Outcome
Performance of clutter suppression and blood flow velocity estimationsurrogate

An SVD-based filter improves clutter suppression in Doppler ultrasound signals, especially for low blood flow velocities, though at the cost of increased computational complexity.

Limitations

  • High computational complexity, which increases considerably for larger temporal windows
