The Jagiellonian PET (J-PET) technology, based on plastic scintillators, has been proposed as a cost effective tool for detecting range deviations during proton therapy. This study investigates the feasibility of using J-PET monitoring by means detailed Monte Carlo simulation 95 patients who underwent therapy at Cyclotron Centre Bronowice (CCB) in Krakow, Poland. 
Approach: Discrepancies between prescribed and delivered treatments were artificially introduced simulations shifts patient...

The PETITION (PET for InTensive care units and Innovative protON therapy) collaboration has developed two Positron Emission Tomography (PET) systems to enable novel clinical applications this imaging modality. Both PET scanners are brain featuring a bore diameter of 300 mm an axial field view length 179 mm. One the system is mobile beside scanner that can be employed in intensive unit (ICU) image vulnerable patients, who cannot moved into regular scanners. second designed proton beam therapy...
