System Architecture of the LabPET Small Animal PET Scanner
To address modern molecular imaging requirements, a digital positron emission tomography (PET) scanner for small animals has been developed at Universite de Sherbrooke. Based on individual readout of
Timing Improvement by Low-Pass Filtering and Linear Interpolation for the LabPET Scanner
Digital processing for positron emission tomography (PET) scanners commonly relies on low frequency sampling (MHz) to reduce power consumption. Timestamps must then be interpolated between samples to
High Rate Photon Counting CT Using Parallel Digital PET Electronics
Recent developments in detectors and electronics enable both positron emission tomography (PET) and X-ray computed tomography (CT) data to be acquired concurrently using the same detection front-end
System Integration of the LabPET Small Animal PET Scanner
TLDR
A digital positron emission tomography scanner for small animals has been developed at Universite de Sherbrooke and features four data recording modes, giving the user the choice to retain data for research or to minimize file size for high coincidence count rate and imaging purposes.
High Rate Photon Counting CT Using Parallel Digital PET Electronics
Recent developments in detectors and electronics enable both positron emission tomography (PET) and X-ray computed tomography (CT) data to be acquired concurrently using the same detection front-end
Timing improvement by low-pass filtering and linear interpolation for the LabPETTM scanner
TLDR
A low-pass filter based interpolation algorithm adding up to 31 samples between original samples was designed to improve both the energy and timing resolution of the LabPETTM scanner.
Sci‐Fri PM Imaging‐10: LabPETtm: A Second‐Generation APD‐Based Digital Scanner for High‐Resolution Small Animal PET Imaging
TLDR
LabPET™ is a novel APD‐based PETscanner with quasi‐individual crystal readout and highly parallel digital architecture for high‐performance in vivo molecular imaging of small animals, offering a fully integrated solution for performing demanding molecular imaging investigations with increased throughput in a busy research environment.
Roadmap to fully-digital PET/CT scanners
TLDR
Different model fits, filtered interpolation and neural networks are compared for timestamping and pulse shape discrimination, and the best methods identified for a roadmap to fully digital PET/CT scanning is presented.
Calibration process for improving Crystal Identification rate in the LabPET™ phoswich detectors
TLDR
To improve the overall scanner identification performance, this work proposes to compute personalized DAQ model reference for every individual channel, and investigates four individual DAQ models based on different minimization of cost functions.
