Product Overview
The Test Pattern is used in X-Ray. The resolution range for each pattern is different. It determines the limiting resolution by inspecting the finished radiograph with a 5-10 powers magnifying glass. This is achieved by looking for the last bar section in which a clear distinction between the line and space can be observed. Read the number corresponding to this line pair section. This represents the line pair resolution for the system. Focal spot size can be determined by observing the regions of blurring which occur when the pattern is radiographed by an X-Ray source of finite dimensions. Radiation from different areas of the focal spot will cause a periodic blurring of the pattern due to penumbra effects. Knowledge of the geometric factors and the distance from the center of the pattern to the region where blurring occurs will permit the calculation of the focal spot size.
