Computed tomography (CT)
CT - Digital Imaging, Reconstruction, Image Quality, and Interpretation
Advanced 40-hour online certification program designed for NDT professionals seeking competency in industrial Computed Tomography (CT), digital radiographic imaging principles, CT acquisition, reconstruction, image quality evaluation, and interpretation practices used in aerospace, defense, additive manufacturing, casting, metrology, semiconductor, and advanced manufacturing applications.
This course goes beyond theory to develop a practical understanding of CT system setup, projection acquisition, effective pixel pitch, spatial resolution, detector performance, image reconstruction, process control, post-reconstruction evaluation, and defect recognition. Participants will gain structured training aligned with industry expectations, real-world implementation practices, and Level 2 responsibilities.
Designed for NDT professionals, inspectors, engineers, and personnel involved in digital radiography, computed tomography, aerospace inspection, additive manufacturing inspection, and advanced manufacturing quality control.
Our CT Level II training includes access to MRA Technique Development Studio™, where students build, modify, and troubleshoot DR/CR/CT techniques in a simulated production environment before touching live equipment.
This course meets the requirements of NAS-410, SNT-TC-1A, and EN 4179.
