Radioterapia, acelerador lineal, control de calidad, análisis de riesgos, control estadístico de procesosResumen
El objetivo principal de este documento es constituir una guía para el diseño del programa de control de calidad en aceleradores lineales (CCAL) con montaje isocéntrico que incorpore los enfoques del control estadístico de procesos (CEP) y del análisis de riesgos. A lo largo del texto se hace hincapié en que la guía no es prescriptiva y se anima a adaptarla a las necesidades específicas de cada centro.
Se presenta una breve descripción de las pruebas recomendadas. Se sugiere un conjunto de pruebas fundamentales y otras complementarias a las que se ha llegado teniendo en cuenta los resultados extraídos de una encuesta a los socios de la SEFM, así como las propuestas de otras sociedades científicas, los comentarios de los fabricantes, y el consenso de este grupo de trabajo. Se proporcionan recomendaciones de frecuencias y tolerancias para aceleradores representativos a título orientativo.
En los apéndices se abordan aspectos funcionales del acelerador lineal y su relación con las pruebas fundamentales del programa de CCAL y se proporciona un ejemplo práctico de CEP aplicado a la variable dosis absorbida por unidad de monitor. Asimismo, se insta a los fabricantes, proveedores de material dosimétrico y gestores a utilizar la guía como referencia para colaborar en el mantenimiento de los equipos al nivel óptimo de calidad y seguridad requeridos.
