Understanding the Basics of Digital Imaging in NDT
In this article:
- Digital Imaging in NDT Explained: Digital Imaging (DI), also known as digital radiography, uses X-ray or gamma-ray radiation with advanced digital detectors to produce high-resolution internal images of materials, enabling fast, accurate, and nondestructive inspections across industries such as aerospace, pressure vessels, and manufacturing.
- CR vs. DR Technologies: Computed Radiography (CR) uses phosphor plates for image capture and digital conversion, offering compatibility with existing equipment, while Direct Radiography (DR) employs digital detector arrays (DDAs) for superior image quality, real-time results, and field-to-facility inspection flexibility; Waygate Technologies supports both with CRxVision, CRxFlex, CRx25P, and DXR series solutions.
- Key Advantages and Components: With core elements including digital detectors, X-ray sources, image processing software, and high-resolution displays, DI offers immediate results, enhanced defect detection, and efficient data management - streamlining workflows and enabling smarter decision-making in nondestructive testing.
Digital Imaging (DI) or digital radiography is a technology in the field of nondestructive testing (NDT). It leverages digital sensors to capture high-resolution images of materials, allowing for detailed internal inspections without causing any damage. Due to its efficiency and accuracy, this method has proven itself in various industries, such as aerospace, pressure vessels and other sectors.
What is Digital Imaging Testing?
DI involves the use of X-ray or gamma-ray radiation to inspect the internal structure of materials. Unlike traditional film radiography, which relies on photographic film, DI uses digital detectors to capture images. These images are then processed and analyzed using advanced software, providing immediate results and facilitating quicker decision-making.
Types of Digital Imaging: CR & DR
- Computed Radiography (CR): CR employs photostimulable phosphor plates to capture images. After exposure, these plates are scanned by a laser to produce digital images. CR is often used as a transitional technology between traditional film and direct digital radiography due to its compatibility with existing X-ray equipment.

Direct Radiography (DR): This method utilizes digital detector arrays (DDAs) to directly capture and transfer images to a computer in real-time. This method offers superior image quality and faster processing times compared to CR, making it the preferred choice for many applications. We provide both portable and stationary systems within our DR solutions. This provides flexibility to perform inspections across a range of environments, from field operations to controlled facility settings.
