Capintec CT Performance Phantom

Capintec CT Performance Phantom

The Capintec CT Performance Phantom is a modular, AAPM Report 1 compliant phantom for evaluating CT scanner performance and quality assurance. A single transparent tank holds beam-width, spatial resolution, high-contrast, and linespread inserts, allowing routine standardization of alignment, spatial uniformity, linearity, resolution, noise, and absorbed dose. Its contrast pins are matched in density across all Capintec CT phantoms, enabling direct comparison between scanners. Manufactured by Capintec and supplied by Meditronix Corporation in India.
