Validation of peneloPET simulations of the Biograph PET/CT scanner with TOF capabilities

Actas de: XXVIII Congreso Anual de la Sociedad Española de Ingeniería Biomédica (CASEIB 2010). Madrid, 24-26 de noviembre de 2010.Monte Carlo simulations are currently widely used in positron emission tomography (PET) imaging for optimizing detector design and acquisition protocols, and for developing and assessing corrections and reconstruction methods. PeneloPET is a Monte Carlo code for PET simulations with basic components of detector geometry, acquisition electronics and material and source definitions. The purpose of the present study was to validate the simulations of the Siemens Biograph PET/CT scanner with TOF capabilities performed with peneloPET. The scanner components incorporate four rings of 48 detector blocks. Each block comprises 13 × 13 matrix of 4 × 4 × 20 mm3. Results were compared with experimental data obtained in accordance with the NEMA-2007 performance measurement protocol done by Jakoby, et al.This work has been supported by MEC (FPA2007-62216), UCM (Grupos UCM, 910059), CPAN (Consolider-Ingenio 2010) CSPD-2007-00042, the RECAVA-RETIC network, ARTEMIS S2009/DPI-1802, European Regional Development, ENTEPRASE grant, PSE-300000-2009-5 and TEC2008-0675-C02-01, Ministerio de Ciencia e Innovación.
