摘要： A trip avoidance X-ray inspection system, typically defining a specialized system that delivers pulsed X-rays, comprises one or more pulse X-ray cameras, each comprising a known set of effects on nucleonic instrumentation; a predetermined set of such shielded X-ray sources; a predetermined set of nucleonic instrumentation operatively in communication with one or more pulse X-ray cameras; and a digital radiography detector adapted to allow, process, or otherwise create an X-ray produced image when disposed proximate predetermined set of nucleonic instrumentation. The pulse X-ray camera is adapted to be disposed at a predetermined distance from predetermined set of shielded X-ray sources.

摘要： A Computed Tomography (CT) system can be deployed by subsea vehicles such as remotely operated vehicles (ROVs) or by divers to perform CT inspections on a subsea structure. In embodiments, a marinized signal source and a marinized flat panel signal detector are positioned at a structure to be inspected subsea and possibly repositioned at different angles about the structure to acquire a series of 2D radiographic images which are then fed to a reconstruction algorithm that produces a 3D reconstructed volume of the structure being inspected.
