Abstract
There are described herein methods and system for generating an inspection image of an object from radiographic imaging. The method comprises obtaining a plurality of digital images of the object positioned between a radiation source and a photon beam detector, the digital images taken at different object-detector distances or source-detector distances to create unique grain diffraction patterns in each one of the digital images, and forming the inspection image from image features common to the digital images at a common scale and removing the unique grain diffraction patterns.

A method for generating an inspection image of an object from radiographic imaging, the method comprising:
- obtaining a plurality of digital images of the object positioned between a radiation source and a photon beam detector, the digital images taken at different object-detector distances or source-detector distances to create unique grain diffraction patterns in each one of the digital images;
- and
- forming the inspection image from image features common to the digital images at a common scale and removing the unique grain diffraction patterns.
A system for generating an inspection image of an object from radiographic imaging, the system comprising:
- a processing unit;
- and
- a non-transitory computer-readable medium having stored thereon program instructions executable by the processing unit for:
- obtaining a plurality of digital images of the object positioned between a radiation source and a photon beam detector, the digital images taken at different object-detector distances or source-detector distances to create unique grain diffraction patterns in each one of the digital images;
- and
- forming the inspection image from image features common to the digital images at a common scale and removing the unique grain diffraction patterns.
A method for inspecting an aircraft component, the method comprising:
- obtaining a plurality of digital images of the aircraft component positioned between a radiation source and a photon beam detector, the digital images taken at different object-detector distances or source-detector distances to create unique grain diffraction patterns in each one of the digital images;
- registering the plurality of digital images to a common scale;
- removing differences between the plurality of digital images at the common scale to generate an inspection image;
- and
- inspecting the aircraft component using the inspection image.
