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 comprising:

• means for associating each of a plurality of sample points of one or more one dimensional (1D) A-Scans of the rotor 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;
• and
• means for generating the 3D visualization of the rotor based on the plurality of voxels by determining a value for a particular one of the plurality of voxels based on a weighted sum of sample points whose kernels cover each particular voxel.

A non-transitory computer readable medium encoded with computer executable instructions for performing a method for generating a three-dimensional (3D) visualization of a rotor, 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 with a particular voxel of a regular three-dimensional grid comprising a plurality of voxels;
• associating a Gaussian kernel with each sample point;
• and
• generating the 3D visualization of the rotor based on the plurality of voxels by determining a value for a particular one of the plurality of voxels based on a weighted sum of sample points whose kernels cover each particular voxel.
