Course Overview
This course provides a comprehensive introduction to digital radiography systems used in aerospace, defense, and advanced manufacturing.
The program emphasizes both theoretical understanding and practical inspection considerations, including system setup, calibration procedures, image acquisition, image quality evaluation, and interpretation techniques. Participants will learn how digital radiography differs from conventional film radiography and how modern digital systems are implemented in industrial inspection environments.
The training also addresses image quality parameters such as contrast, signal-to-noise ratio (SNR), spatial resolution, and detector performance, along with best practices for digital inspection procedures and system verification.
ASNT partners with MR Aerospace Inspections & Consulting to deliver this course. Enrollment is completed through ASNT’s learning management system, while coursework takes place on MR Aerospace Inspections & Consulting's learning platform.
Upon Completion, Learners Will Have Covered:
- Differences between conventional radiography and digital systems
- Computed Radiography (CR) systems and imaging plates
- Digital Detector Array (DDA) technology and system components
- Computed Tomography (CT) technology
- Image quality parameters including contrast, signal-to-noise ratio (SNR), and spatial resolution
- Detector calibration procedures, including gain and offset corrections
- Digital image processing and enhancement techniques
- Inspection techniques for castings, welds, and additive manufacturing components
- Principles of image interpretation and defect recognition
- Applicable industry standards and competency expectations for digital radiography personnel
