About
Jorge G. Barbosa is a leading figure in the development of advanced medical imaging instrumentation, with a primary focus on positron emission mammography (PEM). His key research areas encompass detector physics, depth-of-interaction (DOI) measurement, and the design of high-resolution scanners for breast cancer detection. Barbosa’s major contribution is the pioneering work on the Clear-PEM breast imaging scanner, a dual-head system that leverages avalanche photodiode (APD)-based detector modules. This innovation achieves a critical 2 mm DOI resolution within 20 mm long LYSO:Ce crystals, significantly enhancing image clarity and lesion localization. His foundational overview of the scanner (2008, 11 citations) and its subsequent performance characterization (2009, 8 citations) have laid the groundwork for more precise, non-invasive breast cancer diagnostics. By integrating DOI capability, Barbosa’s research directly addresses the challenge of parallax error in PET imaging, improving the accuracy of tumor detection. His work stands as a notable achievement in the intersection of nuclear medicine and engineering, offering a tangible pathway to earlier and more reliable breast cancer diagnosis, with lasting impact on both clinical practice and detector design.
