A multi-threshold sampling method for TOF PET signal processing
Heejong Kim,Chien-Min Kao,Qingguo Xie,Chin-Tu Chen,L. Zhou,Fukun Tang,Henry J. Frisch,William W. Moses,Woon-Seng Choong +8 more
TL;DR: Details of the results on the timing and energy resolutions by using the multi-threshold method indicate that it is a promising approach for implementing digital PET data acquisition.

- 01 Oct 2007
TL;DR: This work is building a digital library of pulse waveforms generated by using different photo-detectors, scintillator materials, crystal sizes, and read-out electronics of interest in PET to investigate the use of digital signal processing techniques for event processing in positron emission tomography.
A new approach for pulse processing in PET
Qingguo Xie,Chien-Min Kao,Zekai Hsiau,Chin-Tu Chen +3 more
- 01 Oct 2003
TL;DR: This work proposes a new electronic design to overcome design limitations in PET that arise from the need to use high-cost fast analog-to-digital converters (ADCs), and may completely remove the use of ADCs in PET, and possibly the constant fraction discriminator (CFD) as well.

Qingguo Xie,Qingguo Xie,Chien-Min Kao,Rongsheng Xia,Xi Wang,Na Li,Xin Jiang,Li Zhi,Zhi Zhang,Zhonghua Deng,Chin-Tu Chen +10 more
- 08 Mar 2007
TL;DR: The overall architecture of this digital DAQ system for PET is presented, the implementations of several components of the system are described, and the resulting PET data-acquisition system is easier to calibrate and maintain, can generate more accurate event information, and has better extendibility.
Performance characterization of a high-sensitivity small-animal PET scanner
Chien-Min Kao,Qingguo Xie,Yun Dong,Lu Wan,Chin-Tu Chen +4 more
- 01 Oct 2007
TL;DR: Solid evidences supporting the proposed compact, dual-head PET scanner design for achieving an unprecedented sensitivity are reported and initial imaging results generated by the prototypical scanner with phantoms and rats are reported.
