Product Introduction
The LSO:Ce scintillator is an LSO crystal doped with cerium (Ce) ions. The addition of cerium improves the scintillation properties of LSO, making it a more efficient detector of ionizing radiation. LSO:Ce scintillators are widely used in Positron Emission Tomography (PET) scanners, a medical imaging instrument used to diagnose and treat various diseases such as cancer, Alzheimer's and other neurological disorders . In PET scanners, LSO:Ce scintillators are used to detect photons emitted by positron-emitting radiotracers (such as F-18) introduced into the patient. These radiotracers undergo beta decay, releasing two photons in opposite directions. Photons deposit energy within the LSO:Ce crystal, producing scintillation light that is captured and detected by a photomultiplier tube (PMT). The PMT reads the scintillation signal and converts it to digital data, which is processed to produce an image of the distribution of the radiotracer in the body. LSO:Ce scintillators are also used in other applications requiring high-performance scintillation detectors, such as X-ray imaging, nuclear physics, high-energy physics, and radiation dosimetry.
LSO, or lead scintillation oxide, is a material commonly used in radiation detection and imaging applications. It is a scintillation crystal that glows when exposed to ionizing radiation such as gamma rays or X-rays. The light is then detected and converted into electrical signals, which can be used to generate images or detect the presence of radiation. LSO has several advantages over other scintillation materials, including higher light output, faster decay time, excellent energy resolution, low afterglow, and high density. As a result, LSO crystals are commonly used in medical imaging equipment such as PET scanners, as well as in security and environmental monitoring applications.
