This presentation is devoted to introduction of data processing algorithms inJagiellonian PET (J-PET) scanner. In contrast to state-of-the-art PET scanners, in theJ-PET detector multiple small inorganic crystal scintillators are replaced with a longplastic scintillator strips. The operational principles of the J-PET scanner are similarto conventional tomographs, except that the highly accurate time information is ofparamount importance. Therefore, the J-PET scanner demands a preparation of novelmethods on each step of the data processing. The goal of the work presented in thistalk is a development of the signal and image processing algorithms taking intoaccount uniqueness of the J-PET detector. The proposed methods include: signalrecovery 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 exclusivelyin the image space.
