Measure absorbed dose and monitor scanner output for Dose Index QA with the CTDI Phantoms.

Compliance Maintenance
The CTDI Phantom addresses specifications outlined by the FDA (FDA 21CFR 1020.33) and IEC (IEC 60601-2-44, IEC 61223-2-6 and IEC 61223-3-5IEC 60601-2-44).

Configurable to Your Needs
Offered as a 2-piece or 3-piece configuration, it includes nested modules to adapt the phantom to the size required by user protocol. The 2-piece configuration supports adult body and adult head/pediatric body sizes, and the 3-piece option offers an additional pediatric head size.

“The clever phantom and case design allows me to setup and tear down the phantom in 50% of the time compared to my previous CTDI phantom.”
