What is breast tomosynthesis?
Breast tomosynthesis uses high-powered computing to convert digital breast images into a stack of very thin layers or “slices”—building what is essentially a “3-dimensional mammogram”.
During the tomosynthesis part of the exam, the X-ray arm sweeps in a slight arc over the breast, taking multiple breast images in just seconds. A computer then produces a 3D image of your breast tissue in one millimeter layers.
Now the radiologist can see breast tissue detail in a way never before possible. Instead of viewing all the complexities of your breast tissue in a flat image, the doctor can examine the tissue a millimeter at a time. Fine details are more clearly visible, no longer hidden by the tissue above and below.
