With the Cone-Beam Phantom the whole range of image quality parameters measurable at DVT X-ray units, C-arms or angio X-ray modalities with 3D imaging options and at CT scanners with a flat-panel detector can be checked.
Different low contrast sections provide contrasts between 3 and 200 HUs to consider the large variation in low contrast capabilities.
Spatial resolution bar patterns and an additional edge insert determine the system MTF in different orientations. The image contrast and HU-scale section quantifies the machines HU-scale and the bone contrast achieved with different settings. A comparison between different products and technical solutions is possible by comparing the results measured with the Cone-Beam Phantom.
