    Area of Science:

    • Medical Imaging
    • Diagnostic Ultrasound

    Background:

    • Abdominal B scan imaging is crucial for diagnosis.
    • Respiratory and vascular motion can cause organ distortion, reducing image quality.

    Purpose of the Study:

    • To introduce and evaluate continuous raster scanning for abdominal B scans.
    • To improve image resolution and decrease scanning time.

    Main Methods:

    • Utilizing rapid, serial, single-sweep scans at 3-8 mm intervals.
    • Performing scans during suspended respiration.
    • Employing a contact scanner in video mode with a high-resolution store oscilloscope.

    Main Results:

    • Markedly reduced organ distortion caused by respiratory and vascular motion.
