Feixes de elétrons clínicos são compostos por uma mistura de elétrons e fótons de freamento. O espectro de energia de elétrons clínicos entende-se como a justaposição de duas componentes: componente eletrônica e componente fotônica. A componente fotônica ou espectro de fótons contaminantes pode ser obtido através de três vias: 1) Modelamento da fonte primaria; 2) Medição direta; 3) Reconstrução inversa. Neste artigo propõe-se um método de reconstrução inversa do espectro de energia dos fótons contaminantes baseado na fórmula Schiff e o algoritmo de recozimento simulado generalizado.
