- Provides different low contrast sections and spatial resolution bar patterns
- Allows MTF measurements in different orientations
- Multipurpose phantom for comparison of different CT and CBCT scanner solutions
The Cone-Beam Phantom allows to check 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.
Three 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.
In addition to the image quality of cone-beam scanners, the dose can be measured by using a CT Dosimetry Phantom. The CTDI methodology can be applied to all types of cone-beam scanners.
