Scintillators for PET (Positron Emission Tomography) Application
This article discusses how to implement PET medical imaging technology using scintillator arrays. It provides a comprehensive overview of the principles of PET medical imaging technology, the working principle of scintillator pixelated arrays in PET technology, and typical scintillator materials suitable for PET medical imaging, namely LYSO (Ce) cerium-doped yttrium lutetium silicate, GAGG (Ce) cerium-doped gadolinium gallium garnet, and the emerging technology of LaBr3 (Ce)-based scintillator arrays, which are suitable for time-of-flight positron emission tomography (TOF-PET).
What are the Factors Determining Waveplate Retardation Tolerance
This article provides a comprehensive overview of several factors that affect waveplate retardation tolerance.
Why Gold Coating Remains Irreplaceable?
In optical drawings and purchase specifications, the term “Gold Coated” is often highlighted as a standalone requirement. At first glance, it may appear to be a premium or even conservative choice. In practice, however, gold coatings are specified not because they are expensive, but because they solve a set of engineering problems that few other materials can address simultaneously.
