Imaging Plate Design and Use for Radiographic Nondestructive Evaluation

Computed radiography systems require the proper choice of imaging plate for specific applications. Nondestructive testing requires that imaging plates produce acceptable image quality over a wide range of energy conditions, material types, material thicknesses, and configurations. The imaging plate type contributes to the overall image quality and is a key factor in determining productivity. This paper reviews the principles of storage phosphor imaging plates, and it explores the design contribution towards key image quality parameters such as sharpness, noise, and brightness. Usage criteria and guidelines for optimum image quality as a function of radiation level and type will be discussed for the various imaging plate types.
