Imaging Plate Use for Radiographic Nondestructive Evaluation
Conference: Publication Date: 26 October 2015Testing Method:
Nondestructive testing requires that computed radiography imaging plates produce acceptable quality over a wide range of conditions. The imaging plate type determines the overall radiographic image quality and is a key factor in determining productivity. Image quality is heavily dependent upon the imaging plate design. Likewise, the number of use cycles that can be obtained is dependent upon the imaging plate durability and operating environment. This paper reviews the basic principles of storage phosphor imaging plates, and it explores the design contribution towards key quality parameters. Usage criteria and guidelines for optimum image quality and maximized overall use cycles will be discussed for various imaging plate types.
