Women's Imaging: Mammography has been of the best techniques used for 
detecting breast cancer in women. However, women with dense breast tissues usually get false positive results when using mammography or ultrasound scans for breast cancer detection.
On the other hand, tomosynthesis, a new imaging technique, is proving its ability to overcome this problem; the technique is capable of detecting cancer accurately even in women with dense breast tissues. Tomosynthesis was approved previously in Canada and Europe. It is now under clinical trial to get approved in the United States as well.
Tomosynthesis uses small radiation doses to generate 3D images of the breast; those images are reconstructed by a computer to form a series of high resolution slices. Tomosynthesis has a number of benefits such as improved diagnostic accuracy, less need for repeating the technique, and 3D lesion localization. Hologic, the company producing tomosynthesis systems, is sponsoring the clinical trial, hoping to able to offer better breast cancer diagnosis for women.
