It is well documented that tomosynthesis was developed to resolve cases in which, due to a superimposition of tissues, a lesion could be hidden. The detection of early-stage breast cancer has today received a large boost from results of recent scientific research about the 2nd generation tomosynthesis. The angles between exposures are variable (patented) and optimized. Only the useful ones are employed. The x-ray doses delivered at each exposure are variable (patented). Giving a lower overall radiation dose. The scanning angle is wide (40°). For optimal Tomosyntesis (3D) viewing. Tomosynthesis and mammography are no longer separate, but rather combined in the same scan and reconstruction. Two results with a single scan. The reconstruction algorithm is not the one conceived for CT or MRI, but rather of an iterative type. Designed for tomosynthesis. Despite there being a wide scanning angle, the number of exposures is low (13). Reduced, optimized dose. Keeps original pixel size (85 microns) It uses a dedicated 3rd generation amorphous selenium fast detector. Step & Shoot tube motion (ideal for microcalc visualization)
