Reference: D Lee et al, ‘DiffectNet: diffusion-enabled conditional target generation of internal defects in ultrasonic non-destructive testing (NDT)’, Mechanical Systems and Signal Processing, Vol 240, 113454, November 2025. DOI: 10.1016/j.ymssp.2025.113454 System reliability and safety are critical across industries such as semiconductors, energy, automotive, and steel, where even microscopic cracks or defects can severely compromise performance. Because these flaws are hidden from direct visual inspection, engineers have long relied on non-destructive testing (NDT) to assess the internal health of materials and
