1. 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.
