Application of WLS strips for position determination in Strip PET tomograph based on plastic scintillators
arXiv:1311.6129 · doi:10.1515/bams-2013-0103
Abstract
A method of determination of a gamma quantum absorption point in a plastic scintillator block using a matrix of wavelength-shifting (WLS) strips is proposed. Application of this method for improvement of position resolution in newly proposed PET detectors based on plastic scintillators is presented. The method enables to reduce parallax errors in reconstruction of images which occurs in the presently used Positron Emission Tomography scanners.
