What is the light output of LYSO scintillators?

LYSO (Lutetium Yttrium Oxyorthosilicate) scintillators are commonly used in Positron Emission Tomography (PET) and other medical imaging applications due to their advantageous properties. The light output of LYSO scintillators is typically around 76 photons per MeV for gamma-ray interactions. This level of light output is significant because it enhances the detection capabilities of the scintillator by improving the signal-to-noise ratio, leading to better image quality in PET imaging.

The light output translates to the efficiency of energy conversion, where a higher number of emitted photons indicates a more effective scintillation process. This is particularly critical in applications where precise detection of low radiation doses is required, which is often the case in medical imaging.

In contrast, the other options do not accurately reflect the known light output of LYSO scintillators, which is grounded in their material composition and the scintillation process they undergo. This knowledge is essential for technicians and medical imaging professionals who rely on the performance characteristics of scintillators in PET imaging.
