    Area of Science:

    • Medical Imaging
    • Ultrasound Technology
    • Signal Processing

    Background:

    • Assessing ultrasonic A-scan pulse-echo scanner performance is crucial for reliable diagnostic imaging.
    • Conventional methods may not fully capture overall system behavior or specific performance metrics.

    Purpose of the Study:

    • To introduce a practical method for evaluating ultrasonic A-scan pulse-echo scanner performance.
    • To define system performance indices, focusing on resolution and range accuracy, based on a transfer function.

    Main Methods:

    • The proposed method identifies and quantifies an overall system transfer function.
    • The transfer function is used to describe the mapping of reflecting elements into an image.
    • System performance indices are derived from the shape of the transfer function.

    Main Results:

    • A quantifiable method for assessing ultrasonic scanner performance has been developed.
    • Resolution and range accuracy are directly linked to the characteristics of the system transfer function.
    • The developed method provides a framework for objective performance evaluation.

    Conclusions:

    • The system transfer function offers a comprehensive approach to ultrasonic scanner performance assessment.
    • This method provides a more insightful evaluation of resolution and range accuracy compared to conventional techniques.
    • The practical application of this method can lead to improved ultrasonic imaging systems.
