An obstetric test for resolution by ultrasonic echoscopes.

W J Garrett, G Kossoff

    Ultrasonics
    |September 1, 1975
    PubMed
    Summary

    Ultrasonic echoscopy can measure very small fetal distances, like 2mm intercostal distances. This provides a reliable, artifact-free method for assessing ultrasound resolution using fetal anatomy.

    Area of Science:

    • Medical Imaging
    • Fetal Ultrasound
    • Diagnostic Technology

    Background:

    • Assessing the resolution of ultrasonic echoscopes is crucial for accurate medical imaging.
    • Fetal anatomical structures offer potential as natural, artifact-free test objects.

    Purpose of the Study:

    • To evaluate the feasibility of using fetal intervertebral and intercostal distances as a physiological test object for ultrasonic echoscopes.
    • To determine if very small fetal distances can be reliably measured with B-mode echograms.

    Main Methods:

    • Utilizing B-mode echograms to visualize and measure fetal intervertebral and intercostal distances.
    • Employing fetal anatomy as a readily available, artifact-free subject for resolution testing.

    Main Results:

    • Successfully measured very small fetal intervertebral and intercostal distances.
    • Demonstrated the ability to measure intercostal distances as small as 2mm.
    • Validated fetal structures as a suitable test object for ultrasonic resolution assessment.

    Conclusions:

    • Fetal intervertebral and intercostal distances are measurable using B-mode echograms.
    • These fetal measurements provide a valuable, artifact-free physiological test object for assessing ultrasonic echoscope resolution.
    • The technique allows for the measurement of minute distances, such as 2mm intercostal distances, highlighting its precision.
