APPLICATION OF THE COMPRESS SENSING THEORY FOR IMPROVEMENT OF THE TOF RESOLUTION IN A NOVEL J-PET INSTRUMENT

Nowadays, in positron emission tomography (PET) systems, a time of flight (TOF) information is used to improve the image reconstruction process.In TOF-PET, fast detectors are able to measure the difference in the arrival time of the two gamma rays, with the precision enabling to shorten significantly a range along the line-of-response (LOR) where t

Background: The circulation of vehicles, motorized or not, is a risky activity that can lead to a traffic accident in which all road users can be affected.Road accidents generate high personal, labor, health and economic costs, as well as civil, administrative and even criminal responsibilities.Therefore, it is necessary to carry out a correct inve
