Ultrasonic Doppler Imaging Apparatus Using Novel Plane-Wave Synthesis and Control Method Therefor

Plane-Wave-Synthesis-Based Ultrasonic Doppler Imaging Technology

This technology relates to an ultrasonic Doppler imaging apparatus and control technology that simultaneously improves frame rate and sensitivity by applying a novel plane-wave synthesis technique.

Conventional plane-wave-based Doppler imaging has faced a trade-off between high-speed imaging and sensitivity, limiting blood-flow measurement range and resolution. This technology selectively synthesizes a variable number of frames among continuously incident frames to generate a Doppler image.

As a result, it can improve the resolution and sensitivity of Doppler imaging while maintaining a measurable blood-flow velocity range, thereby contributing to better medical ultrasound diagnostic performance.

Key Features:

• It generates a Doppler image by variably synthesizing plane-wave incident frames.
• It is controlled to secure both a high frame rate and high sensitivity.
• It is advantageous for improving resolution without reducing the measurable blood-flow velocity range.
