- Suitable for image quality check-ups and constancy testing of Breast CT and other Cone-Beam CT Systems
- Determination of spatial resolution in any direction (3D-MTF)
- 4 different targets (air, -3% contrast, +3% contrast and bone)
The main body of the phantom consists of water-equivalent material and contains three sections for the evaluation of the contrast-to-noise ratio (CNR), spatial resolution (3D MTF), uniformity, geometric accuracy and image noise. The first section includes 4 different targets suitable for accurate contrast to noise ratio (CNR) evaluation. The homogenous second section allows to validate the uniformity and noise performance of the imaging system. The third section accommodates a 12 mm PTFE sphere placed centrally to perform a MTF in three dimensions.
