QRM-10120 Cone-Beam Phantom

Cone-Beam Phantom
Compact design for testing diagnostic and cone-beam CT imaging performance
Low-contrast resolution
2 different models with different low contrast sections. The basic version offers contrasts between -3 HU and -20 HU in one section. In addition, the expert version offers three low contrast sections with contrasts between -3 and -200 HU.

Spatial resolution
Using the spatial resolution bar patterns, you can assess the in-plane resolution of the system in a direct visual manner up to 30 lp/cm. Additional edge inserts determine the system's MTF in different orientations.

CT Values Accuracy
As part of the QA, the CT values should be monitored  regularly. The image contrast and HU-scale section quantifies the machine's HU-scale and the bone contrast achieved with different settings.

Noise & Homogeneity
Signal-to-Noise Ratio (SNR) and homogeneity can be checked using plain sections in our phantoms. The geometric accuracy section can be used to analyze image distortion.
