The QRM MicroCT Wire Phantom is based on a cylinder containing two wires in air or solid material aligned parallel to the phantom axis of rotation. One of the wires is slightly off center, the second one away from the center in order to allow estimating image quality in the periphery.
Point Spread Function (PSF) and Modulation Transfer Function (MTF) can so easily be investigated.
Different wire diameters are available as well as different materials and positions of the wires inside the phantom.
Please specify the material the wires should placed in (air or solid plastics). In both cases the contrast will be high enough for evaluation.

Standard phantoms are scaled down from the diameter of an average human trunk (32 cm) to that of a fat mouse or lean rat (32 mm). Other dimensions as well as inserts with substances other than specified here can be produced upon request.
