The all digital PET system is attracting more and more attentions due to its flexibility, scalability, reusability and upgradability. Based on the Trans-PET formerly developed by us, we are trying to fulfill online parameter calibration of the all digital PET system. The ability of thorough and quick online parameter calibration will make the system well adaptive to application variation, environment...
We are developing, at the Huazhong University of Science and Technology, a small-animal positron emission tomograph (PET) scanner that has two new features. Firstly, it uses detector modules that are based on a new digital readout electronics previously investigated and reported by us. Secondly, it can arrange the detector modules into various scanner geometries for different imaging needs. In this...
An all-digital data acquisition (DAQ) system for positron emission tomography (PET) events is presented. The advantages of digital DAQ for PET system have been recognized recently. Sampling rate faster than 200Mhz is required when LSO scintillation pulses are directly digitized. That make it unaffordable to implement a PET system with all digital DAQs, due to numerous channels in PET system and costly...
