The Basic Detector Module (BDM) | PET Detector Module is a novel all-digital PET detector module that generates a digital scintillation pulse when an incoming gamma photon interacts with the detector blocks. It consists of a pair of LYSO/SiPM detector blocks and a multi-channel digital data aquisition (DAQ) board. The signal from the LYSO/SiPM detector blocks are directly sampled by the multi-channel digital DAQ board. The samples are sent out via Ethernet connector through UDP. By developing the software to collect and analyze the resulting samples, the user could extract information on the gamma photon and develop his or her own application quickly.
The BDM | PET Detector Module is the first digital detector that is compatible with the magnetic field. The detector uses digital and modular design concepts and provides a full range of solutions and detectors for digital PET/CT and PET/MRI, as well as other multi-mode systems.
The BDM | PET Detector Module makes the designing and upgrading of a PET system easier. Using several modules and a PC, one could easily and quickly set up a PET system. It only requires users to develop the software and the mechanical system.
