A quality performance indicator for digital x-ray micro-radiography system has been developed. It was used for nondestructive testing on microstructure object. A set of testing apparatus for image quality indicator (IQI) was developed from acrylic sheets that were cut carefully using laser cutting tool. These IQI apparatus imitated common standard such as step wedges, holes indicator, and lines/wires tester. The IQI step wedge was used to measure the relative x-ray penetration capability. The IQI holes indicator was used to measure the Modulation Transfer Function (MTF) of the imaging system and the IQI lines/wires tester was used for pixel calibration and image spatial resolution determination. From this experience, this simple, low cost, customized, quick made and accurate IQI set fulfilled the performance testing requirement procedure.
