Patent No. EP4397966 (titled "A Method For Scanning Of Objects In A Scanning Apparatus") was filed by Rolls Royce on Dec 5, 2023. The application was issued on Aug 13, 2025.
A method for scanning multiple turbine blades in a CT scanner, where the blades are positioned in an alternate head-to-toe arrangement on a rotatable support to reduce material thickness variation during scanning. The blades are disposed between the x-ray source and detector, with their leading edges adjacent to the trailing edges of adjacent blades, to minimize beam hardening and scatter artifacts. This configuration enables simultaneous scanning of multiple blades with improved image quality and reduced scanning time compared to traditional single-blade scanning methods.
