The Abdomen Phantom – Low Contrast Spheres (model 53-03) is engineered to replicate a uniform-density abdomen with built-in low-contrast spheres of varying diameters, enabling detailed assessment of low-contrast resolution, detectability sensitivity, and image quality consistency on multi-detector CT scanners.
This phantom is especially useful for imaging facilities looking to evaluate or compare their abdominal acquisition protocols or train users in optimizing scan parameters for contrast-to-noise trade-off.
Applications:
- Low-contrast resolution testing in abdominal imaging
- Performance constancy monitoring of multi-slice CT scanners
- Abdominal protocol optimization
- Inter-system comparison and image quality improvement tracking
Specifications
- Dimensions: approximately 300 × 200 × 150 mm
- Material: homogeneous block simulating the density of abdominal parenchyma
- Inserts: multiple low-contrast spheres of varying diameters embedded in the homogeneous matrix
- Evaluation parameters: image uniformity, low-contrast resolution, detectability sensitivity, and scanner performance constancy
- Design: liquid-free, stable over time, easy to position and handle
