Catphan 500/600 CT Phantoms.

Comprehensive CT Performance Measurements Catphan® Phantoms are internationally recognized for measuring the MAXIMUM obtainable performance of axial, spiral and multislice CT scanners. The Phantom Laboratory and physicist, David Goodenough, Ph.D., have worked together to develop the Catphan® Phantoms. The new Catphan® designs are based on three decades of scientific research and direct field experience in the evaluation of medical imaging equipment. These phantoms are used to complete comprehensive performance evaluations of axial, spiral and multislice CT scanners and to implement quality assurance programs. The Catphan® Phantoms are constructed from modules that fit snugly into a durable 20cm housing. With the exception of the water tank module used in the Catphan® 424, all Catphan® modules are made from solid-cast materials. Solid-cast construction eliminates material absorption of water, freezing and leaks associated with water bath phantoms, as well as, problems related to varied water sources. Tests - Summary
