About

N. Oliveira is a leading researcher in medical imaging physics, with a primary focus on the development of advanced Positron Emission Tomography (PET) systems for breast cancer detection. Their major contributions center on the Clear-PEM breast imaging scanner, a pioneering dual-head Positron Emission Mammography (PEM) device. Oliveira’s work was instrumental in demonstrating the scanner’s unique capability to measure depth-of-interaction (DOI) within LYSO:Ce crystals, achieving a remarkable 2 mm resolution. This innovation significantly enhances image quality and lesion detectability in dedicated breast imaging. Their foundational overview paper (2008, 11 citations) established the system’s design and DOI potential, while a subsequent characterization study (2009, 8 citations) validated its full-system performance. These highly cited works have shaped the field of dedicated PET mammography, offering a path toward more precise and comfortable breast cancer diagnostics. Oliveira’s research stands as a key achievement in the integration of avalanche photodiode (APD) technology with DOI measurement, advancing the state of the art in nuclear medicine instrumentation.
