A PET scan uses a radioactive tracer to give 3D information on how the tissues and organs in the body are functioning. The radioactive tracer may be injected, swallowed or inhaled, depending on the type of study. The tracer collects in areas of interest corresponding to the disease or condition being studied.The tracer concentration in the body is then imaged using the PET scanner which detects the radiation it emits.
The high-performance, functional imaging that is now possible with PET has made it the industry standard for cancer staging and every year, the number of clinical applications of PET is increasing. New applications for PET are becoming mainstream and authorized by the world’s health care providers and with this comes a drive for increasing PET performance at lower cost. SiPM sensors have now replaced PMTs as the de-facto choice for high-performance PET systems.
This page gives details of recommended products and related academic papers as well as a variety of other information that may be of use to someone interested in SiPM for PET applications.
J-Series sensors have been specifically optimized for fast timing applications such as ToF-PET, they have the highest PDE and the highest fill-factor TSV package on the market. J-Series Arrays are also available.
Detection Efficiency of C-Series and J-Series Compared to the Emission of LYSO
Normalized PDE curves for the C-Series (MLP package) and the J-Series (TSV package) and the normalized emission spectrum for LYSO. In practice, the absolute peak value of the C-Series PDE curve is 41% and 51% for the J-Series.
Coincidence Resolving Time of J-Series Sensors with Various Scintillation Crystals
The CRT values as a function of bias voltage for different crystals, attained with the fast outputs from two MicroFJ-30035-TSV sensors in coincidence. These results are from J.Cates and C.Levin of Stanford University.
