ABSTRACT:
The present invention provides an apparatus and a method of use and construction of Anthropomorphic Mammography Phantoms. The phantoms resolve deficiencies that currently exist in the practice of mammography x-ray imaging. The mammography phantom provides mammography practitioners a training tool in the practice of proper patient breast positioning and in optimal patient x-ray exposure. The mammography phantom can be used to generate x-ray images similar to mammography patient x-ray images. The mammography phantom simulates normal breast tissue and tissue irregularities and anomalies associated with various known breast pathologies such as microcalcifications, cysts, tumors, etc. The mammography phantom preferably comprises the shape of an upper torso of a woman including one or two breast simulators which can vary in size, density, compressibility, and stretchability. The mammography phantom is preferably constructed such that the breast simulators can be detached from the upper torso phantom, used independently, and/or replaced on the torso thereby enabling the mounting of a variety of breast simulator types. The upper torso of the mammography phantom also preferably provides a rib cage (with pectoralis major muscle) for the mounted breast simulators, providing an additional element of realistic patient simulation.
