WebPremium PMT Design PET Detector. The Celesteion PET detector offers a unique design that incorporates photomultiplier tubes (PMT) of different sizes. This design provides a … WebA Photomultiplier Tube (PMT) is a photon detector, that outputs a current signal when a photon is detected. The current is converted into a voltage signal by a transimpedance amplifier. The voltage signal is ultimately converted to a digital signal by a digitizer. Below is some information about PMTs that is commonly true regardless of the model.

WebAs for response time: most fluorescent signals can be amplified rapidly, but detectors for others, such as transmembrane currents, respond slowly, making slow scanning speeds necessary. The PMT voltage determines the amplification of the PMT. An increase of 50 volts corresponds to a factor of about two more in gain. WebThis design provides a performance with highest performing Time-of Flight available on a PMT system. This coupled with the largest bore in PET imaging makes it a powerful tool for radiation oncology departments who look to incorporate PET data in therapy planning. 4mm x 4mm Lu-based crystals Unique detector design of mixed PMT sizes penncon model showhttp://ptceurope.com/documents/PTCOG52%20P295%20Amplifier%20Developments%20at%20MGH.pdf tnt 844 method
