The ECT/SPS-LG/A large sphere can represent either a solid tumor or a tumor with a necrotic core by providing two separately fillable compartments: the inner core and the outer shell. Typical volumes are approximately 26 mL (core) and 80 mL (shell), enabling controlled contrasts for quantitative assessment of reconstruction, sensitivity, and attenuation/scatter effects in PET/SPECT.
Applications:
- Simulation of solid tumor or tumor with necrotic core
- Quantitative studies: apparent size, wall thickness, and mass
- Research and reconstruction validation in nuclear imaging
Specifications
- Inner core: ID 37 mm; OD 39 mm; wall 1 mm; volume ≈ 26 mL
- Outer shell: ID 60 mm; OD 63 mm; wall 1.5 mm; volume ≈ 80 mL
- Filling: core and shell independently fillable
- Material: clear PMMA
Models
- ECT/SPS-LG/A - Large Spherical Shell
