Real-time color B-scan ultrasonography

N R Bronson, N C Pickering

    Journal of Clinical Ultrasound : JCU
    |September 1, 1975
    PubMed
    Summary

    A new real-time color B-scan ultrasonoscope displays echo amplitude quantitatively using color, improving visualization over grayscale. This portable, inexpensive device offers dynamic imaging for clinical applications, particularly in ophthalmology.

    Area of Science:

    • Medical Imaging
    • Ultrasound Technology
    • Ophthalmology

    Background:

    • Traditional grayscale ultrasound lacks quantitative echo amplitude information.
    • Display limitations like "blooming" hinder detailed visualization in black and white systems.

    Purpose of the Study:

    • To describe the development of a novel real-time color B-scan ultrasonoscope.
    • To present early clinical results and demonstrate the instrument's capabilities.

    Main Methods:

    • Development of a real-time B-scan ultrasonoscope utilizing color display.
    • Conversion of echo amplitude data into binary coded decimal for ten distinct color steps.
    • Integration of circuitry for portability and cost-effectiveness.

    Main Results:

    • The color display provides more quantitative echo amplitude information compared to grayscale.
    • Real-time imaging allows visualization of dynamic changes during examinations.
    • Elimination of cathode ray tube "blooming" enhances image clarity.

    Conclusions:

    • The developed ultrasonoscope offers enhanced quantitative imaging through color representation.
    • The portable and affordable unit shows promise for clinical use, with initial applications in ophthalmology.
