Case Study: Flexible Digital Detector Arrays vs. Computed Radiography
Presentation Description
Radiography codes and standards require that single wall exposure techniques be utilized whenever practical. Pipeline field radiography currently utilizes film or computed radiography (CR) for single wall viewing of pipeline welds, whereby each technology exhibits tradeoffs for image artifacts and time to image. Flexible digital detector arrays (DDAs) produce images with acceptable quality and minimal artifacts, in the shortest time to image possible. Application of flexible DDA technology to pipeline welds is new to the industry. Examples of flexible DDA single view radiographs are compared to CR as part of this paper.
