This Spatial Resolution Module (also known as a line pair test phantom) is a precision calibration tool designed for evaluating the spatial resolution performance of industrial radiography, digital X-ray, and non-destructive testing (NDT) systems. It is widely used in quality control, equipment calibration, and compliance testing across aerospace, automotive, and manufacturing industries.

Multi-Resolution Line Pairs: Equipped with effective line pairs corresponding to 1.6, 1.8, 2.0, 2.2, 2.6, 3.0, 3.4, and 3.8 lp/mm, covering a wide range of testing requirements for both low and high-resolution imaging systems. Three Material Options: Constructed with three different radiopaque materials – aluminum, stainless steel, and tungsten – allowing multi-material resolution verification for diverse testing scenarios. Clear Visualization: Encapsulated in a high-transparency, durable acrylic housing for easy imaging and long-term use, with a compact 3D structure for stable placement during testing. Reliable Calibration: Ensures accurate assessment of image sharpness, edge definition, and system performance, helping users validate and optimize their NDT equipment.
