Line pairs per millimeter or LP/mm is a measurement of spatial resolution that is, how small a space you can perceive. Spatial resolution is important if you want to see a very small item, such as the tip of a No. 8 endo file on a radiograph.

If focusing is accurate, the '0' on the lens calibration chart should be the sharpest point on the image. The other numbers should get blurrier as you move away from the '0'. If any number above the 0 is sharper, then your lens is doing something called back focus.

Imatest IT (Industrial Testing) is a set of Application Programming Interfaces (APIs) that allow developers to access Imatest's powerful image quality analysis tools in their own custom applications.

The test patterns are used to evaluate film-screen systems, magnification techniques and resolution capabilities of x-ray imaging systems. The patterns consist of various lead thicknesses. The respective thickness is usually specified on each pattern.
