Leverage a sophisticated design to comply with guidelines, and more.
The only phantom needed to meet American College of Radiology (ACR) accreditation guidelines
Versatility permits checking of multiple parameters, efficiently
With the CT ACR 464 Phantom, you gain a multi-functional resource for your department.
Not only is it essential for compliance, it allows the testing of: positioning and alignment; CT number accuracy; slice thickness; low contrast detectability, image resolution; image uniformity; spatial resolution; inter and intra plane distance measurement accuracy; and more.
- Single phantom permits checking multiple parameters
- Compact design makes the phantom safe to store and easy to transport
- Automated software allows for fast and simple reporting of results

CT ACR 464 Phantom Body Ring
The CT ACR 464 Phantom Body Ring can easily be inserted into the 464 Body Ring adapter to permit fast imaging QA for a better indication assessment of a scanner’s performance with large patients.
CT ACR 464 Phantom Extensions
The CT ACR 464 Phantom Extensions plates accurately represent scatter effects from widebeam CT scanners, thus eliminating the need to add a water bolus or other material when measuring the Phantom.
