Resumen
En este trabajo se presenta el desarrollo de un sistema para reconstruir el interior de objetos industriales utilizando rayos gamma, el cual está conformado por dos subsistemas. El primero obtiene las imágenes radiográficas y el segundo reconstruye imágenes planas correspondientes a cortes del objeto, utilizando tomografía de transmisión y de emisión. Ambos contienen módulos para simular radiografías y tomografías industriales de rayos gamma. El modelo de simulación desarrollado puede utilizarse para diseñar tomógrafos gamma de aplicaciones específicas, determinándose parámetros como el número óptimo de proyecciones y las energías necesarias para la reconstrucción de los objetos involucrados.
Descriptores: Tomografía gamma.
Abstract
In this work, we present the development of a system to reconstruct the inner contend of industrial objects using gamma rays. This system is conformed by two subsystems. The first subsystem obtains radiographic gamma images and the second reconstructs 2D images corresponding to slices of the object, using transmission and of emission tomography. Both subsystem has a module to simulate gamma radiography and industrial gamma tomography, respectively. The developed simulation module can be used to design gamma tomography for specific applications, determining parameters like the number of projections and the necessary energy for the reconstruction of the involved object.
Keywords: Gamma tomography.
