[Ultrasonic dynamic focus data reordering design based on FPGA]

Area of Science:

• Medical Imaging
• Ultrasound Technology
• Digital Signal Processing

Context:

• Analog reordering and folding in ultrasound systems cause signal attenuation and hinder beam steering.
• Color Doppler diagnostic instruments face limitations with existing analog techniques.

Purpose:

• To propose a novel digital reordering method for dynamic focusing data in ultrasound imaging.
• To address the limitations of analog signal processing in achieving precise beam steering.

Summary:

• The proposed digital reordering method consists of two stages: multiplier-based bit reordering and switch selection-based byte reordering.
• This approach effectively processes dynamic focusing data for ultrasound applications.
• The design demonstrates feasibility and meets performance requirements with reduced resource utilization.

Impact:

• Enables improved beam steering capabilities in color Doppler ultrasonic diagnostic instruments.
• Reduces signal attenuation inherent in analog processing methods.
• Offers a resource-efficient solution for advanced ultrasound data processing.
