The QRM MicroCT Bar Pattern Phantom was designed to provide a tool for direct visible measurement of spatial resolution in Micro–CT. The chip offers a good alternative for indirect methods to evaluate spatial resolution in high res X-ray imaging modalities. The phantom comprises two chips, one orientated in-plane and one in perpendicular (axial) orientation. The chips are placed on a slim support in air or in a full resin cylinder with highmechanical accuracy respectively.

The 5 x 5 mm˛ chip contains bar- and point- pattern with diameters ranging from 5 to 150 µm line/point thickness. The depth of the structures varies between 80 and 120 µm. The different structures on the chip are arranged in such a way over the chip, that spatial resolution can be evaluated in the center as well as in the periphery of the image/chip in a single measurement. The cylinder, including two chips, is available in 20 mm diameter phantom (in air) or 8 mm diameter phantom (in resin). Other diameters upon request.

The phantom is available with bar pattern chips placed in resin or in air!
