摘要： A method and apparatus for three-dimensional (3D) visualization and analysis for automatic non-destructive examination of a rotor bore using ultrasound. Data is acquired by scanning the rotor bore with an ultrasound pulser/transducer producing a plurality of one-dimensional ultrasound scans, each scan having a plurality of sample points. Each sample point is associated with a voxel of a regular 3D grid having a plurality of voxels. A Gaussian kernel is associated with each sample point and a value for a particular voxel is determined based on a weighted sum of sample points whose kernels cover the particular voxel. The values for the other voxels of the regular 3D grid are determined similarly. A 3D visualization of the rotor bore can be displayed to a user.

摘要： Interactive virtual inspection of modeled objects is provided. A graphic user interface facilitates interaction between a Data Visualization and Analysis application and the inspector. The Data Visualization and Analysis application acquires non-destructive examination data that is collected with reference to an industrial component under evaluation. The acquired non-destructive examination data is transformed into a visualization defined by a volumetric representation that is rendered on at least one display device as at least one view representative of the component under evaluation. The inspector may navigate the volumetric representation to investigate the integrity of the industrial component including non-surface conditions thereof.

摘要： A phased array ultrasonic testing system for examining discontinuities in turbine or generator rotor bores formed within turbine or generator rotors of a turbine or generator rotor assembly. The system includes a phased array ultrasonic transducer structured to be coupled to a surface of the rotor bore at a first location in order to emit an ultrasonic beam toward a second location of the rotor bore which is to be examined. The system further includes a control system with a computer and a controller for programming, emitting, and steering the ultrasonic beam via at least one, two-dimensional phased array transducer, thereby precisely and accurately inspecting the area of interest. Computer control of the beam permits the number of inspection locations and the number of different transducer wedges to be reduced providing for an efficient, timely inspection.
