Digital Signal and Image Processing in Jagiellonian Positron Emission Tomography

Dissertation of Lech Raczyński is devoted to the presentation of data processing algorithms in the Jagiellonian PET (J-PET) scanner. The work describes original and inventive methods of signal and image reconstruction. I consider their development a great achievement due to the complex methodology of determining the position in the J-PET scanner based on measurement of the light pulses propagation time in long plastic scintillators. The author applies modern methods of data processing, like compressive sensing theory and total variation regularization technique. For their evaluation both experimental and simulation data of the J-PET scanner were used. This work is an important contribution to the field of PET. The presented results are crucial to the success of the J-PET project.
