Abstract

Se presenta un equipamiento científico/tecnológico destinado a la generación de un haz de fotones convergentes para usos en radioterapia u otras aplicaciones. Este equipamiento consiste de conformar adecuadamente, por medio de la aplicación de campos magnéticos y/o eléctricos, un haz de electrones provenientes de un acelerador lineal (LINAC), los cuales interceptan perpendicularmente la superficie de un material curvo de cierto radio de curvatura (ánodo), generando así rayos-X. La interacción de los electrones con los átomos del material del ánodo genera rayos-X con una distribución angular-espacial no isotrópica, con una mayor concentración en la dirección focal, definida por la geometría del ánodo. Por la parte posterior del ánodo, se coloca un colimador curvo, con un radio de curvatura adecuado, constituido por un arreglo de un gran número de pequeños orificios los cuales apuntan hacia el punto focal. Este dispositivo permite la transmisión de los rayos-X en la dirección focal únicamente. En la Figura resumen se presenta un esquema típico de la invención aquí presentada.
