Performance evaluation of the LabPET™ APD-based digital PET scanner
The LabPETTM is a fully digital avalanche photodiode (APD) based PET scanner designed for state-of-the- art molecular and genomic imaging of small animals and demonstrated with in vivo images of rats and mice.
The Hardware and Signal Processing Architecture of LabPET™, a Small Animal APD-Based Digital PET Scanner
A new fully digital APD-based scanner architecture is proposed wherein nuclear pulses are sampled directly at the output of the Charge Sensitive Preamplifier (CSP) with one free-running ADC per channel to explore new digital signal processing algorithms borrowed from other fields like command and control theory, as well as advanced heuristics such as neural networks.
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
Real time digital signal processing implementation for an APD-based PET scanner with phoswich detectors
A highly parallel data acquisition system based on an integrated analog front-end and a high-speed fully digital signal processing section that directly samples the output of each preamplifier and feeds the sampled data into a field programmable gate array VirtexII PRO from Xilinx, which allows up to 64 channels to be processed simultaneously.
Real time coincidence detection system for digital high resolution APD-based animal PET scanner
A centralized, fully digital, FPGA-based coincidence detection system has been developed for the LabPET APD-based scanner that detects prompt coincidences and evaluates random coincidences using both a delayed-window coincidence and the singles count rate.
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
Real time digital signal processing implementation for an APD-based PET scanner with phoswich detectors
Recent progress in advanced digital signal processing provides an opportunity to expand the computation power required for real time extraction of event characteristics in avalanche photodiode
Crystal Identification Based on Recursive-Least-Squares and Least-Mean-Squares Auto-Regressive Models for Small Animal Pet
A crystal identification method based on adaptive filter theory using an auto-regressive (AR) model is proposed to enable real time crystal identification in a noisy environment.
Real Time Implementation of a Wiener Filter Based Crystal Identification Algorithm
The recently launched LabPETtrade, a small animal Avalanche PhotoDiode (APD)-based PET scanner with quasi-individual readout and massively parallel processing, makes it possible to acquire real-time
