“…In particular, the amplification avalanche of a single primary electron performed with an efficiency close to 100% and the gas amplification between 10 4 to 10 6 , generate high spatial and temporal resolution useful to obtain the same and better quality of images than the standard mammographic units, demanding 10 times lower dose delivered to the patient [4]. MPGDs as advanced gas-avalanche detectors offer also a high rate capability, a great spatial resolution, a large sensitivity area, operational stability and manufacturing process compatible with high volume industrial production allowing new applications [21][22][23][24].…”

Early detection of small calcifications in mammograms is considered the best preventive tool of breast cancer. However, existing digital mammography with relatively low radiation skin exposure has limited accessibility and insufficient spatial resolution for small calcification detection. Micro Pattern Gaseous Detectors (MPGD) and associated technologies, increasingly provide new information useful to generate images of microscopic structures and make more accessible cutting edge technology for medical imaging and many other applications. In this work we foresee and develop an application for the new information provided by a MPGD camera in the form of highly controlled images with high dynamical resolution. We present a new Super Detail Image (S-DI) that efficiently profits of this new information provided by the MPGD camera to obtain very high spatial resolution images. Therefore, the method presented in this work shows that the MPGD camera with SD-I, can produce mammograms with the necessary spatial resolution to detect microcalcifications. It would substantially increase efficiency and accessibility of screening mammography to highly improve breast cancer prevention.
