9.1 From Analog to Digital Mammography

Mammography is considered the best tool for the early detection of breast cancer and puts the highest demands on the imaging systems, among all the medical applications. In fact, both high spatial and contrast resolutions are needed for visualizing small structures as microcalcifications and for differentiating breast tissues with very similar X-ray absorption properties, such as tumor opacities. With these requirements, mammography necessitates very small detecting elements and high signal-to-noise ratio (SNR): it is one of the most challenging imaging technologies and is the most recent X-ray-based ...
