What Does Real-time Radiography (RTR) Mean?
Real-time radiography is a nondestructive (NDT) method whereby invisible X-rays are used to produce digital images. During this method, X-rays are discharged on one side of the object, which then penetrate the object and are absorbed by sensors on the opposite side. The captured rays are converted to visible wavelengths of light and are used to produce real-time images.
This digital radiography method is commonly used to detect corrosion in pipelines. The penetrative nature of X-ray radiation makes this technique especially ideal for revealing corrosion under insulation (CUI).
Real-time radiography is also known as real-time radioscopy or fluoroscopy.
