Early diagnosis is one of the most important factors in the survival of patients diagnosed with breast cancer. To aid in the early detection of breast cancer, a new technology, called tomosynthesis imaging is being developed. The idea behind tomosynthesis imaging is to "look" at the breast from different points of view by obtaining x-ray flat images from different angles while the breast does not move, and then mathematically combine these flat images into a three-dimensional image. The benefit of these three dimensional images is that the radiologist can look at the different tissues of the breast in their real positions, as opposed to all the tissues being "flattened" into a flat image, like that of a normal mammogram. The flat images in mammograms bring about the possibility that normal healthy tissue sometimes covers up malignant tumors, making them harder, and sometimes impossible, for the physician to see. In addition, this "flattening" sometimes generates what appears to be suspicious tissue, but is in reality a superposition of normal healthy tissue. This effect results in performing an increased number of biopsies that end up being negative for breast cancer. Since tomosynthesis images of the breast show the tissues in their real position, these effects can be avoided. It has already been shown by various research labs, including ours, that this kind of imaging does in fact result in better visualization of lesions compared to conventional two-dimensional imaging, even without performing tomosynthesis under ideal conditions.
