Abstract
SPECT es una modalidad no invasiva de diagnóstico por imagen, utilizada en la actualidad con fines clínicos principalmente en oncología, cardiología y neurología. En el Laboratorio de Imagen Médica del Hospital Gregorio Marañón se está desarrollando un sistema denominado FSPECT diseñado para aplicar esta técnica en animales de laboratorio. El presente PFC tiene como objetivo la implementación de una herramienta software que permita realizar las correcciones o calibraciones necesarias para el correcto funcionamiento del sistema FSPECT, ofreciendo al usuario final una interfaz sencilla de manejar que le permita abstraerse del procesado interno realizado. La aplicación implementada permite llevar a cabo correcciones en tres subsistemas del aparato. Estos son la electrónica de adquisición de datos, los elementos detectores y la geometría de adquisición. En cada etapa de corrección se parte de un conjunto de datos que se procesan con la aplicación desarrollada para generar ficheros de corrección que se aplicarán sobre los datos adquiridos de forma subsecuente en el aparato. _________________________________________________________________________________________________________________________
SPECT is a non-invasive diagnostic imaging technique, with clinical application in oncology, cardiology and neurology among other areas. In the Medical Image Laboratory at Hospital General Universitario Gregorio Marañón a system denominated FSPECT is being developed which has been designed to apply this technique to small laboratory animals. The objective of this work is the implementation of a software tool for the calibration of the FSPECT system. The idea is to provide the user with a simple interface to acquire calibration data and to generate the calibration files required for the appropriate usage of this system. The application implemented allows the user to acquire calibration data and to obtain calibration files for three differentiated parts of the FSPECT. These are: Data acquisition electronics, detector elements and mechanical system (geometry errors due to mechanics tolerances). Each one of the correction stages calibration data are acquired, following predefined procedures and processed with the developed application to obtain correction files, which will be applied to the subsequently acquired data.
