    Area of Science:

    • Ultrasound imaging
    • Medical physics

    Context:

    • Linear-array ultrasound systems are widely used in medical diagnostics.
    • The proximal curved edge artifact can affect image quality and diagnostic accuracy.

    Purpose:

    • To demonstrate the appearance of the proximal curved edge artifact.
    • To simulate the artifact using a waterbath.
    • To provide a physical explanation for the artifact.

    Summary:

    • The proximal curved edge artifact was observed in five clinical cases using linear-array systems.
    • Simulations in a waterbath successfully replicated the artifact.
    • The underlying physical principles causing this artifact are discussed.

    Impact:

    • Improved understanding of ultrasound artifact generation.
    • Potential for enhanced image interpretation and artifact reduction strategies.
    • Aids in quality assurance for ultrasound equipment and techniques.
