Sistema de planificación de tratamientos, verificación de planes, garantía de calidad, estado de referencia inicial, auditorías, test end-to-endResumen
El contenido del documento refleja las recomendaciones de la SEFM para el control de calidad y uso seguro de los sistemas de planificación de radioterapia externa. Se hace una exposición inicial de los motivos, consideraciones generales y principales novedades a tener en cuenta en los sistemas de planificación actuales, para pasar a analizar detalladamente la caracterización de las unidades de tratamiento y los parámetros que hay que tener en cuenta en el modelado de las mismas, haciendo especial hincapié en aquellos que tienen que ver con el colimador multilámina. En el documento se distinguen tres secciones diferentes que tratan de abarcar todo aquello que influye en que el producto del sistema de planificación, el plan de tratamiento, tenga la mejor calidad y seguridad asociada: control de calidad del sistema de planificación, garantía de calidad del proceso de planificación y verificación de planes de tratamiento, todo ello siempre manteniendo la visión que proporciona el análisis de riesgos asociado.
El programa de control de calidad se establece en tres pasos: estado de referencia inicial, controles periódicos y controles tras actualizaciones. Añadido a esto, se analiza el proceso de planificación y cómo garantizar la calidad en el mismo por medio de procesos globales (auditorías y pruebas end-to-end), evaluación de planes y sistematización relacionada con la protocolización y las soluciones de clase. Por último, se describen las herramientas de verificación de planes y sus limitaciones, las métricas asociadas así como las estrategias de verificación posibles. Todo el documento culmina con un último capítulo que resume todas las recomendaciones basándose en lo expuesto y concreta las tolerancias a utilizar en cada etapa.
