Silicon Detector for Low-Light Levels Detection in Near-Ultraviolet Region

摘要

Molecular imaging is a state-of-the-art technology for noninvasive cell and molecular viewing. It is used for imaging the metabolism of various analytes such as proteins, nucleic acids or other molecules in the body through the attachment of radioactive tracers or positron sources. The high-energy radiation is received by surrounding detectors, which typically use scintillators to make a conversion to visible light. Most of the existing scintillator technologies that are fast enough for the molecular imaging area operate in the ultraviolet (UV) spectrum. Hence, they need detectors optimized for this spectrum.
