About

C. S. Ferreira is a leading researcher in the field of medical imaging, with a primary focus on the development and characterization of advanced Positron Emission Tomography (PET) systems for breast cancer detection. Their most significant contributions center on the **Clear-PEM breast imaging scanner**, a pioneering dual-head Positron Emission Mammography (PEM) device. Ferreira’s work was instrumental in demonstrating the scanner’s unique capability to measure depth-of-interaction (DOI) with a 2 mm resolution using APD-based detector modules and LYSO:Ce crystals. This innovation dramatically improved image quality and lesion localization in breast imaging. Their key publications, including an overview of the scanner (2008, 11 citations) and a detailed performance characterization (2009, 8 citations), have provided the foundational data for this technology. By validating the system’s high-resolution performance, Ferreira’s research has helped pave the way for more precise, non-invasive breast cancer diagnostics, marking a notable achievement in the advancement of dedicated PET instrumentation.
