Tomografía computarizada: proceso de adquisición, tecnología y estado actual

Abstract: <p>La tomografía computarizada (CT) es una técnica de escaneo no invasivo ampliamente aplicada en sectores como la medicina, la industria y la geología. Esta técnica permite la reconstrucción tridimensional de la estructura interna de un objeto que es iluminado con una fuente de rayos-X. La reconstrucción se forma con imágenes bidimensionales de cortes transversales del objeto. Cada corte se obtiene a partir de las medidas de fenómenos físicos como la atenuación, la dispersión y la difracción de los rayo… Show more

“…With the fractal geometry methods of Box Dimension and Mass Dimension, the fractal dimension that characterizes the roughness that occurs in the hip joints as a result of the decalcification of bone tissues was determined, in such a way that when the effect of loss of bone mass as a fractal this explains the pathological conditions of osteopenia and osteoporosis [10], [16], [19].…”
