Mamede Bruno Melo Mendes Andréa Vidal Ferreira Biología 2008 NEMA NU 4 Normalization Image Quality Small Animal PET A small animal positron emission tomograph (LabPET GE 4) image acquisition is done by 1536 independents channels. Differences in the rate counting of each channel must be corrected so as not compromise image quality. Equipment user manual recommends that normalization of the detectors efficiency be made as often as possible and always whenever there are hardware or software parameters changes - included, but not limited to channels parameters adjustments, electronic cards replacements, channels activation or inactivation or software update. This work evaluates the normalization effects on the image quality parameters. PET image acquisition and analysis were performed using recommended parameters by the NEMA NU 4-2008 standards. Image was reconstructed in different ways using different normalization files. The tests performed indicated that the image quality parameters do not vary significantly with different normalization data. Therefore, a high frequency routine of normalizations is not justified, suggesting a periodical frequency of one month for this procedure. 2019 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280899018 en http://www.redalyc.org/revista.oa?id=7222 Brazilian Journal of Radiation Sciences application/pdf Sociedade Brasileira de Proteção Radiológica - SBPR Brazilian Journal of Radiation Sciences (Brasil) Num.3 Vol.7 |
