Three-dimensional image processing method for visualizing e.g. inner ear, involves comparing function value of luminosity of voxels and adjoined voxels with luminosity threshold for several times by changing threshold at each comparison

摘要

The method involves selecting a sub volume of images in a volume corresponding to initial acquisition of three-dimensional images by a magnetic resonance imaging (MRI), and choosing a luminosity threshold. Voxels are selected in the sub-volume by comparing a function value of a luminosity of the voxels and adjoined voxels with the threshold. The comparison operation is iterated several times by changing the threshold at each iteration, and a three dimensional (3D) image is reconstructed. Independent claims are also included for the following: (1) a three dimensional (3D) imaging system having processing unit for implementing a three dimensional (3D) image processing method (2) a computer program comprising instructions for implementing a three dimensional (3D) image processing method.
