    This study presents an improved mirror system for high-resolution ultrasonic imaging, reducing reverberations for clearer breast imaging results without compromising focusing performance.

    Area of Science:

    • Medical Imaging
    • Acoustics
    • Biomedical Engineering

    Background:

    • High-resolution ultrasonic imaging, particularly for breast imaging, requires large-aperture transducers.
    • Existing mirror systems for achieving large apertures face challenges with reverberations.

    Purpose of the Study:

    • To redesign mirror systems for ultrasonic imaging to mitigate reverberation issues.
    • To maintain or improve focusing performance in large-aperture ultrasonic systems.

    Main Methods:

    • Implementation of design modifications to the mirror system.
    • Utilization of thin metal reflectors to minimize reverberations.

    Main Results:

    • Reverberations within and between mirror components were significantly reduced.
