RECONSTRUÇÃO 3D DE OSSOS A PARTIR DE IMAGENS DE RAIO-X

Abstract

This paper presents a method for building a three dimensional model of the lower leg bone (tibia) from a human, from X-ray images. The methodology adopted to obtain the 3D object is deforming the model until it corresponds to X-ray images (front and left and right sides) of the tibia. We used the following algorithms for X-ray images segmentation and three-dimensional modeling: Canny, Border Following, Free Form Deformation (FFD) and deformation algorithm developed in this work. The viewing application defined and implemented shows the three-dimensional image of the bone of the tibia resulting from deformation of the 3D object. The experimental results demonstrate the possibility of representing the real human bone obtained from X-ray images into a 3D model, however, a great difficulty for this activity was the number of images available for the project
