Abstract

La presente invención se relaciona con un aparato de terapia por radiación que incluye un compensador que tienen una pluralidad de hojas para dividir el haz de radiación en rayos, cada uno de los cuales puede ser atenuado efectiva e individualmente sobre un intervalo de atenuaciones mediante el control del ciclo o régimen de trabajo de la posición de las hojas entre los estados abierto y cerrado. Un aparato para controlar el conteo del compensador para la dispersión de la radiación a través de la desconvulsión de un mapa de etlum (terma) y calcular un sinograma para controlar el compensador en una variedad de ángulos alrededor de un paciente que utiliza proyecciones iteradas hacia adelante y hacia atrás eficientemente calculadas en el espacio de frecuencia.
