En este artículo se revisarán las bases físicas de la técnica PET, la detección de fotones y la creación de sinogramas. Junto a los principios de la formación de imágenes PET, se presentarán las técnicas de retroproyección y la técnica de reconstrucción de imágenes estadística iterativa. Adicionalmente, se discutirá la implementación de la corrección del rango del positrón y la inclusión del tiempo de vuelo de la información, esto con el propósito de mejorar el contraste de imágen y ruido de la señal.
In this paper we review the basics of PET and discuss the fundamental principle of the physics of PET, the detection of photons and the creation of sinograms. The principles of PET image formation as described with the presentation of the basic back-projection technique and the now well established statistical iterative image reconstruction technique. We also discuss the implementation of the positron range correction and the inclusion of the time-of-flight information for the purpose of improve image contrast and signal to noise.
