    Area of Science:

    • Biomedical Engineering
    • Medical Imaging Technology

    Background:

    • Conventional B-scanners are expensive and may not be suitable for all applications.
    • A-scan units are widely available but limited in their imaging capabilities.

    Purpose of the Study:

    • To design and construct a simple, cost-effective multi-element transducer array.
    • To adapt an existing A-scan unit into a real-time, hand-held section scanner.
    • To explore applications in medical imaging, particularly for non-invasive cardiac imaging.

    Main Methods:

    • Connecting transducer elements in groups of four to achieve a finer stepping interval.
    • Integrating the multi-element array with an A-scan unit.
    • Evaluating the system's performance as a real-time section scanner.

    Main Results:

    • Successful design and construction of a functional multi-element transducer array.
    • Demonstration of the array's capability to convert an A-scan unit into a real-time scanner.
    • Achieved finer stepping intervals compared to discrete transducers.

    Conclusions:

    • The developed multi-element transducer array provides an inexpensive alternative to conventional B-scanners.
    • The system is suitable for real-time, non-invasive imaging applications, including dynamic cardiac imaging.
