Mammographic Accreditation Phantom

The 156 Mammographic Accreditation Phantom has been the #1 phantom listed by the ACR since the start of the MQSA program in 1994. The 156 provides the physical standard baseline for assuring the quality of the images produced by your mammographic system. The phantom simulates the x-ray attenuation of a 4.2 cm slab of compressed human breast composed of 50% adipose tissue and 50% glandular tissue.
