Micro-CT-BarPattern

The Micro-CT Bar Pattern Chip Phantom is a perfect tool to assess in-plane and axial spatial resolution of any Micro-CT system in a direct visible manner.

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 in a full resin cylinder with highmechanical accuracy.

The 5 x 5 mm² chip contains bar- and point- pattern with diameters 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 singlemeasurement. The cylinder, including two chips, is available in any favored diameter down to 7mm.

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