BODY MODEL AND METHOD FOR BIMODAL THREE-DIMENSIONAL BREAST IMAGING QUALITY DETECTION

摘要

Disclosed are a body model and method for bimodal three-dimensional breast imaging quality detection. The body model comprises a three-dimensional breast-shaped phantom structure (1) prepared with an agarose gel comprising polyethylene inside, wherein the polyethylene is a radiation equivalent material of adipose tissue under the X ray, and the relaxation time of the hydrogen proton in the agarose gel in the 3T magnetic field is equivalent to that of human adipose tissue, and a breast tissue catheter phantom (3) and a lobule phantom of the mammary gland (4) distribute inside the breast-shaped phantom structure (1). The body model can be used for image quality detection and analysis in two imaging systems, i.e. magnetic resonance and mammography. The material is flexible, and can be compressed and imaged on a mammography platform, and can also be placed vertically in a magnetic resonance breast coil to carry out a tomography, realizing two imaging ways with one body model, and broadening the application range.
