Siemens' Acuson S2000 ABVS (automated breast volume scanner) is an ultrasound system intended for the early detection and diagnosis of breast cancer. A conventional mammography often doesn't allow a proper diagnosis of possible cancers in the patient, especially if their tissue is too dense, or if the cancer is positioned in areas not easily reachable by standard mammography equipment. With the ABVS, the doctor can inspect the patient's breast using a moving ultrasound scanner, which easily reaches all areas of the breast, offering a precise tridimensional view of the tissue.
