The Flangeless Esser PET Phantom (model PET/FL/P) is a cylindrical performance phantom for PET system evaluation.
Its flange-free design simplifies positioning within the scanner’s field of view and ensures reproducible measurements for acceptance testing, routine QA and research.
The phantom includes:
- Cold rods (Ø 4.8 to 12.7 mm) for spatial resolution evaluation
- Solid spheres (Ø 9.5 to 31.8 mm) for assessing contrast, visible volume and SUV accuracy
It supports testing of tumor detectability, reconstruction sensitivity, attenuation/scatter correction and SUV quantification.
Recommended by the American College of Radiology (ACR), it serves as a benchmark for PET QA and quantitative imaging protocol validation.
Applications:
- Tumor detectability and contrast evaluation
- SUV and reconstruction accuracy verification
- PET QA and acceptance testing
- Sensitivity, attenuation and scatter studies
- Research
