Proper operation of the hardware and software of a SPECT Gamma Camera depends on its correct configuration and quality control. These are essential to obtain clinically valid images. In spite of the fact that these are recommended by the equipment manufacturer, these operations are not described in the manuals. The objective of the present work is to propose a unique method for the extrinsic quality control of any SPECT Gamma Camera manufactured to NEMA – IEC specifications. For this purpose, an automatic mixing module has been built to prepare uniform field phantoms, so as to carry out the quality control of the SPECT equipment. The module consists of an automatic mixer and a dummy (phantom). Thanks to the homogeneity of two‐ phase mixtures, we can obtain extrinsic correction maps which will serve to evaluate the quality of the equipment. This operation depends upon the homogeneity ...

El buen funcionamiento del Hardware y Software de una Cámara Gamma SPECT, depende de la correcta configuración y del control de calidad. Estas acciones son esenciales para la obtención de imágenes clínicamente válidas. Los fabricantes, recomiendan estas acciones, sin embargo, no existen técnicas descritas en los manuales correspondientes a estos equipos. Los objetivos del presente trabajo consisten en proponer una técnica exclusiva para el control de calidad extrínseca de una Cámara Gamma SPECT de fabricación variable que estén reconocidas en NEMA, IEC. Para ello se construye un módulo mezclador automático para preparar fantomas de campo uniforme, mediante el cual nos permitirá realizar los controles de calidad de los equipos SPECT. El módulo está constituido por un equipo mezclador automático y de un maniquí (denominado fantoma). Mediante la homogeneidad de mezclas bi...
