US 2008/0290302 A1 · Suspension System and Scanning Method

Abstract

A method and apparatus for performing a radiation scan of a structure involve arranging a source of penetrating radiation and a radiation detector at opposed ends of a radiation path through the structure, oriented in such a way that the source emits radiation along the path through the structure and the detector is capable of detecting the radiation after it has passed through the structure and monitoring the radiation emitted from the source that is detected by the detector. At least one continuous loop of a cable is mounted on the structure between at least two fixed locations on the structure so that the cable is movable along its length relative to the structure, and the at least one of the source of penetrating radiation and the radiation detector are fixed to the cable.

Dependent claims

A method of carrying out a radiation scan of a structure comprising the steps of

i. arranging a source of penetrating radiation and a radiation detector at opposed ends of a radiation path through the structure, said source and detector being oriented in such a way that the source emits radiation along the path through the structure and the detector is capable of detecting the radiation after it has passed through the structure along said path:
ii. monitoring the radiation emitted from the source that is detected by the detector;
wherein at least one of the source of penetrating radiation and the radiation detector is fixed to a continuous loop of a cable, said cable being mounted on said structure such that the cable is movable along the direction of its own longitudinal axis relative to the structure.

An apparatus for performing a scan of a structure comprising:

a) at least one continuous loop of a cable, said cable being mounted on said structure and being movable along its length relative to the structure,
b) a source of penetrating radiation mounted in a fixed position on said loop so that it is movable relative to the structure with the loop and adapted to emit radiation through said structure,
c) a radiation detector mounted in a fixed position on said loop so that it is movable relative to the structure with the loop and adapted to receive radiation from said radiation source,
d) means for monitoring the radiation received by the detector which has been transmitted from said source through a path through the structure defined by a linear path from said source to said detector.
