seminarium, na którym zostanie wygłoszony referat pt.:
„Digital Signal and Image Processing in Jagiellonian Positron Emission
Tomography”
Referuje: Dr Lech Raczyński (NCBJ)
Abstract:
This presentation is devoted to introduction of data processing algorithms in Jagiellonian PET (J-PET) scanner. In contrast to state-of-the-art PET scanners, in the J-PET detector multiple small inorganic crystal scintillators are replaced with a long plastic scintillator strips. The operational principles of the J-PET scanner are similar to conventional tomographs, except that the highly accurate time information is of paramount importance. Therefore, the J-PET scanner demands a preparation of novel methods on each step of the data processing. The goal of the work presented in this talk is a development of the signal and image processing algorithms taking into account uniqueness of the J-PET detector. The proposed methods include: signal recovery based on samples of a waveform registered on photomultiplier output,reconstruction of position of interaction of annihilation photon in the scintillator strip,classification of PET events types and image reconstruction that operates exclusively in the image space.
