Abstract
A bimodal three-dimensional mammary gland imaging quality detecting phantom and method, which includes: a three-dimensional breast appearance phantom structure made of agarose gel containing polyethylene, which is a radiation equivalent material of adipose tissues under X-rays, the relaxation time of hydrogen protons in the agarose gel under a 3T magnetic field is equivalent to that of human adipose tissues, and mammary gland tissue duct phantoms and phantoms of lobules of mammary gland are distributed in the breast appearance phantom structure. The phantom can be used for the image quality detection and analysis of mammary gland imaging by the systems of magnetic resonance and mammography, the material is elastic and can be compressed on a mammography platform for imaging, and the phantom can also be vertically placed in the magnetic resonance mammary gland coil for tomography, so two imaging modes of one phantom are achieved, and the application range is expanded.
