B-Scan (Brightness-Scan)
A two-dimensional cross-sectional display of ultrasonic data showing depth (vertical axis) and distance along the scanning path (horizontal axis), with signal amplitude represented by brightness. B-scans provide visual representation of internal material structure and defect locations within a vertical plane. This presentation mode is more intuitive than A-scans and helps visualize the exact position and extent of discontinuities within the material thickness.
