Three-Dimensional Visualization and Analysis Method and System for Non-Destructive Examination of a Rotor Bore using Ultrasound

An apparatus for generating a three-dimensional (3D) visualization of a rotor bore comprising:

• means for associating each of a plurality of sample points of one or more one dimensional (1D) A-Scans of the rotor bore with a particular voxel of a regular three-dimensional grid comprising a plurality of voxels;
• means for associating a Gaussian kernel with each sample point;
• means for determining a value for a particular one of the plurality of voxels based on a weighted sum of sample points whose kernels cover the particular voxel.

A computer readable medium encoded with computer executable instructions for performing a method for generating a three-dimensional (3D) visualization of a rotor bore, the computer executable instructions defining steps comprising:

• associating each of a plurality of sample points of one or more one dimensional (1D) A-Scans of the rotor bore with a particular voxel of a regular three-dimensional grid comprising a plurality of voxels;
• associating a Gaussian kernel with each sample point;
• determining a value for a particular one of the plurality of voxels based on a weighted sum of sample points whose kernels cover the particular voxel.
