Digital Signal Processing Techniques to Improve Time Resolution in Positron Emission Tomography

Monzó Ferrer, José María; Esteve Bosch, Raul; Lerche, Christoph Werner; Ferrando Jódar, Néstor; Toledo Alarcón, José Francisco; Aliaga Varea, Ramón José; Herrero Bosch, Vicente; Mora Mas, Francisco José (Institute of Electrical and Electronics Engineers (IEEE), 2011-08)

Coincidence time resolution is one of the most important issues in PET detectors. Improving this resolution is required to increase the noise equivalent count rate (NECR) that reduces the noise in the reconstructed images. ...
Fixed Point of Interpolative Rus-Reich-Ciric Contraction Mapping on Rectangular Quasi-Partial b-Metric Space
