Ultrasound Plane-Wave Compressed Sensing Reconstruction Method Using Intra-frame and Inter-frame Joint...

Area of Science:

• Medical Ultrasound
• Signal Processing
• Image Reconstruction

Background:

• Ultrasound plane-wave imaging offers high frame rates but generates large data volumes, creating system bottlenecks.
• Compressed sensing reduces sampling/transmission burdens but often yields lower image quality due to reliance on signal sparsity.

Purpose of the Study:

• To improve ultrasound signal reconstruction accuracy and image quality by incorporating prior knowledge of plane-wave imaging.
• To address the limitations of traditional compressed sensing methods in ultrasound.

Main Methods:

• Proposed a plane-wave multi-hypothesis prediction compressed sensing reconstruction method inspired by video compression.
• Applied multi-hypothesis prediction and residual reconstruction to enhance plane-wave data.
• Evaluated two hypothesis acquisition schemes using preceding, subsequent, and reference frames.

Main Results:

• The multi-hypothesis prediction method reduced signal reconstruction errors and eliminated image artifacts compared to sparsity-based methods.
• Improved hypotheses enhanced signal reconstruction and image quality, leading to higher contrast.
• Demonstrated superior performance in reconstruction errors and image quality on PICMUS and ARFI datasets.

Conclusions:

• The proposed method offers a significant improvement over traditional compressed sensing techniques for ultrasound imaging.
• This approach effectively reduces sampling and transmission complexity in ultrasound systems.
• Results validate the method's efficacy on public datasets, enhancing diagnostic capabilities.
