Inhalt:
Positron emission tomography (PET) is a key technique in medical imaging. The Jagiellonian PET (J-PET) Collaboration developed a novel whole-body PET scanner based on plastic scintillators, which reduce the high cost of PET scanners. However, the J-PET scanner requires particular methods for each step of data processing. Lech Raczyński presents new approaches to developing signal and image processing algorithms that take into account the specifications of the J-PET detector.
