The PET Detector BDM II is a high-resolution, fully digital PET detector. The BDM II uses LYSO probes to directly output information on Gamma photon energy, position, and time. Users can quickly build a high-resolution PET system for teaching and research by selecting one or more BDM II detectors.
The PET Detector BDM II employs a new digital method called Multi-Voltage Threshold (MVT) to digitize scintillation pulses. This method outputs digitized information on pulse energy, position, and time. The traditional equal-time interval sampling is upgraded to equal-voltage interval sampling, combined with the prior shape characteristics of the scintillation pulse, to obtain energy, position, and time information. This method is especially suitable for high-speed pulse information acquisition.

REAL LIFE EXAMPLES
A mini-PET detection system for teaching and studying: Using one BDM PET detector module and a normal computer system, you can set up a mini-system for PET coincidence detection and imaging. Such systems provide you the original event pulse from the detector in digital waveform. You can use it to study and teach the PET detection process and principle.
A PET system for imaging: With several BDM | PET Detector Modules and a high-performance computer system, you can quickly setup a PET system.
