产品介绍：

The Mammographic Accreditation Phantom Model 156 is
designed to test the performance of a mammographic
system by evaluation of the system’s ability to image
small structures similar to those found clinically. Objects
within the phantom were designed to simulate micro-calcifications,
fibrous structures in ducts, and tumor-like masses,
small structures that are important in the early detection
of breast cancer. Test objects within the phantom
range in size from those that should be visible on any system
to objects that will be difficult to see even on the best
mammographic systems.
