Abstract
Some embodiments include a radiographic inspection system, comprising: a drive mechanism configured to move along a structure; a detector attached to the drive mechanism; a radiation source attached to the drive mechanism and positionable relative to the detector such that a width of the structure casts a radiation shadow on an active area of the detector; and control logic coupled to the detector and configured to: receive an image from the detector; generate side wall loss information based on the image; and generate bottom wall loss information based on the image.

A radiographic inspection system, comprising:
- a drive mechanism configured to move along a structure;
- a detector attached to the drive mechanism;
- a radiation source attached to the drive mechanism and positionable relative to the detector such that a width of the structure casts a radiation shadow on an active area of the detector;
- and
- control logic coupled to the detector and configured to:
- receive a single image from the detector;
- generate side wall loss information based on the single image;
- and
- generate bottom wall loss information based on the single image.
A method of operating a radiographic inspection system, comprising:
- positioning a drive mechanism, detector, and radiation source around a structure;
- generating a single image of a section of the structure using the detector and radiation source including at least a width of the structure;
- generating side wall loss information based on the single image;
- and
- generating bottom wall loss information based on the single image.
A radiographic inspection system, comprising:
- means for generating radiation;
- means for generating a single image based on the radiation coupled to the means for generating radiation;
- means for moving the means for generating radiation and means for generating the single image based on the radiation;
- and
- means for generating side wall loss information and bottom wall loss information based on the single image.
