Resum
El uso de sistemas de imagen portal de MV puede simplificar el control de calidad de los equipos, y permite realizar nuevas pruebas sin aumentar el tiempo de medida. Por otra parte, no son los instrumentos de medida de dosis recomen-dados en los documentos de consenso, por lo que es preciso realizar un estricto proceso de validación específico para utilizarlo con dicho fin. En este trabajo se exponen un conjunto de pruebas de validación de las medidas y una serie de controles de calidad que se han implementado.
