| dc.description.abstract | El objetivo del presente trabajo se centró en evaluar el desempeño del tomógrafo por emisión de positrones Biograph mCT 64 de PET-CT aplicando las pruebas de resolución espacial, fracción de dispersión, cuentas pérdidas y medidas aleatorias, sensibilidad y calidad de imagen recomendadas en la publicación NU 2-2007 de la National Electrical Manufactures Association, NEMA. Los resultados obtenidos fueron analizados y comparados con los otorgados por el fabricante para los casos en que el fabricante da los respectivos parámetros. Se concluye que el tomógrafo por emisión de positrones Biograph mCT 64 de PET-CT tiene muy buenas características de funcionamiento, además la calidad de la imagen mejora el contraste al incorporar la informacióon a la modelización de la respuesta del equipo para compensar la degradación de la resolución espacial, PSF en los algoritmos TrueX HD. | spa |

The results obtained were analyzed and compared with those given by the manufacturer for cases in which the manufacturer gives the respective parameters. It is concluded that the Positron Emission Tomograph PET-CT Biograph mCT 64 has very good performance characteristics, in addition the image quality improves the contrast by incorporating the information to the modeling of the response of the equipment to compensate degradation of spatial resolution, PSF in TrueX HD algorithms. | spa |
