Image Quality Phantoms

Phantoms simulate human tissue to test CT performance. They contain structures that evaluate resolution contrast and noise. Regular testing ensures consistent image quality. Phantoms are essential for QA programs.

Dose Measurement Phantoms

These phantoms measure radiation output from CT scanners. They help verify dose accuracy and consistency. Proper measurement ensures patient safety. Dose phantoms support regulatory compliance.

Geometry Phantoms

Geometry phantoms test alignment and slice thickness. They ensure accurate spatial representation. Regular checks maintain scanner precision. Geometry testing is vital for high quality imaging.

Routine QA Protocols

Facilities perform QA tests weekly monthly and annually. Results are documented and reviewed by medical physicists. Proper QA ensures reliable scanner performance. Phantoms play a central role in CT quality control.
