phantoms

Phantoms are specially designed objects that mimic human tissue or organs, used primarily in medical imaging and testing. They help ensure that equipment like MRI, CT scans, or radiation devices produce accurate results without exposing patients to unnecessary radiation. Made from materials that simulate the density and properties of real tissues, phantoms can test, calibrate, and validate medical devices, improving diagnostic quality and safety. Essentially, they serve as stand-ins or test tools that help healthcare professionals optimize imaging technology in a controlled, consistent way.
