Abstract
Some embodiments include a radiographic inspection system, comprising: a detector; a support configured to attach the detector to a structure such that the detector is movable around the structure; a radioisotope collimator; and a collimator support arm coupling the detector to the radioisotope collimator such that the radioisotope collimator moves with the detector.
Claims20
A radiographic inspection system, comprising:
- a detector;
- a support configured to attach the detector to a structure such that the detector is movable around the structure;
- a radioisotope collimator;
- and
- a collimator support arm coupling the detector to the radioisotope collimator such that the radioisotope collimator moves with the detector;
- wherein the collimator support arm is adjustable to change a position and/or rotation of the radioisotope collimator relative to the detector.
3 more elements
A method, comprising:
- exposing a radioisotope;
- acquiring a plurality of images using a detector positioned with a structure between the exposed radioisotope and the detector;
- rotating the detector around the structure between the acquisition of at least two of the plurality of images;
- retracting the radioisotope only after completing the acquiring of the plurality of images.
1 more element
A system, comprising:
- means for generating radiation;
- means for collimating the radiation;
- means for generating images in response to the radiation;
- means for attaching the means for generating images in response to the radiation to the means for collimating the radiation and for adjusting a position and/or rotation of the means for collimating the radiation relative to the means for generating images in response to the radiation;
- and
- means for movably attaching the means for generating images in response to the radiation to an object.
3 more elements
A radiographic inspection system, comprising:
- a detector;
- a support configured to attach the detector to a structure such that the detector is movable around the structure;
- a radioisotope collimator;
- a radioisotope disposed within the radioisotope collimator and configured to emit radiation towards the detector;
- a collimator support arm coupling the detector to the radioisotope collimator such that the radioisotope collimator moves with the detector;
- and
- control logic configured to rotate the detector and the radioisotope collimator around the structure;
- wherein the control logic is further configured to generate scanning parameters based on at least one of the structure and the radioisotope.
