CT scan test phantom PURE CTDI

torsoheadpediatric

Description
This CT phantom for medical imaging is designed to measure the Dose Index (DI) and related CTDI metrics. It comprises three PMMA cylinders representing a pediatric head, an adult head and a body. The pediatric head nests into the adult head, which in turn nests into the body for multi-configuration testing and compact storage.

Allows evaluation of:

• Dose Index (DI)
• CTDI100 (central)
• CTDI100 (peripheral)
• CTDI free air
• CTDIvol (weighted CTDIw)
• CTDIw (weighted CTDI100)

Specifications

• Material: PMMA (polymethyl methacrylate) cylinders
