Resumen (es)
este artículo explica que las bases Daubechies puede ser usadas para diseñar algoritmos de reconstrucción localizada de imágenes tomográficas desde las proyecciones almacenadas en matrices de datos dispersos. Los desarrollos de tales algoritmos reducen significativamente la cantidad de exposición a los rayos X trasmitidos en la tomografía, evitando daños colaterales a largo plazo en pacientes, en órganos como pulmones, corazón, y también en lesiones de la médula
Resumen (en)
This article explains that Daubechies bases can be used to design algorithms that reconstruct localized tomographic images from sparse data matrix projections. The developments of such algorithms significantly reduce transmission tomography’s amount of X ray exposure, avoiding collateral damage in patients over the long-term, in organs such as the lungs, heart, and also spinal injuries.
