L'algorithme de rétroprojection filtrée ne se prête pas facilement à l'introduction des données a priori. Ceci nous a conduits à aborder le problème de la reconstruction de la fonction d'une manière totalement différente. 1, record 1, French, - algorithme%20de%20r%C3%A9troprojection%20filtr%C3%A9e

La mayoría de los equipos tomográficos de medicina nuclear, utilizan para la reconstrucción topográfica de sus imágenes, el algoritmo de retroproyección filtrada. Este es de carácter analítico, y está basado en la transformada de Radón, y el teorema del corte de Fourier. Por ser de fácil implementación y muy rápido en la obtención de los cortes transversales, su uso se generalizó a pesar de tener el inconveniente de generar un artificio típico denominado "estrella" que degrada sensiblemente la calidad de las imágenes. 1, record 1, Spanish, - algoritmo%20de%20retroproyecci%C3%B3n%20filtrada
