Experimental Analysis of Commercial Optical Methods for Foot Measurement

open access: yesSensors, 2022
Due to the increasing trend of online shopping, shoes are more and more often bought without being tried on. This leads to a strong increase in returns, which results in a high financial as well as ecological burden. To prevent this, feet can be measured

Application of the compress sensing theory for improvement of the TOF resolution in a novel J-PET instrument

open access: yesNukleonika, 2016
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
