This article is focused on data acquisition system (DAQ) designed especially to be used in positron emission tomography (PET) or single-photon emission computed tomography. The system allows for continuous registration of analog signals during measurement. It has been designed to optimize registration and processing of the information carried by signals… (More)
Novel time-of-flight positron emission tomogra-phy (TOF-PET) scanner solutions demand, apart from the state-of-the-art detectors, software for fast processing of the gathered data, monitoring of the whole scanner, and reconstruction of the PET image. In this article, we present an analysis framework for the novel STRIP-PET scanner developed by the J-PET… (More)
We discuss computing issues for data analysis and image reconstruction of PET-TOF medical scanner or other medical scanning devices producing large volumes of data. Service architecture based on the grid and cloud concepts for distributed processing is proposed and critically discussed.
Photomultipliers are commonly used in commercial PET scanner as devices which convert light produced in scintillator by gamma quanta from positron-electron annihilation into electrical signal. For proper analysis of obtained electrical signal, a photomultiplier gain curve must be known, since gain can be significantly different even between photomultipliers… (More)
A positron emission tomography (PET) scan does not measure an image directly. Instead, a PET scan measures a sinogram at the boundary of the field-of-view that consists of measurements of the sums of all the counts along the lines connecting the two detectors. Because there is a multitude of detectors built in a typical PET structure, there are many… (More)
A general-purpose trigger and readout board (TRBv2) with on-board DAQ functionality is currently being developed as a replacement of the existing HADES electronics (DAQ and parts of the FEE) as well as for the PANDA Mini Drift Chamber (MDC) readout . The first version has been sucessfully integrated into the data aquisition of the HADES detector (TRBv1… (More)
A multipurpose 128-channel Time to Digital Converter (TDC) electronics based on the HPTDC  with on-board DAQ functionality has been developed. The main usage will be the RPC-detector upgrade of the HADES-detector (2600 channels) with a needed time resolution of < 100ps and the required possibility to measure the time of the rising and falling edge of the… (More)
The J-PET scanner, which allows for single bed imaging of the whole human body, is currently under development at the Jagiellonian University. The discussed detector offers improvement of the Time of Flight (TOF) resolution due to the use of fast plastic scintillators and dedicated electronics allowing for sampling in the voltage domain of signals with… (More)
