Patent ID: 7315609

Claim:
A non-destructive inspection apparatus for inspecting a structure, comprising: a first probe configured for traveling over a first surface of the structure under inspection, the first probe comprising: at least one magnetic coupling device; and at least one x-ray source for emitting radiation for inspecting the structure as the first probe is moved over the first surface of the structure; and a second probe configured for traveling over a second surface of the structure for through transmission inspection, the second probe comprising: at least one magnetic coupling device for magnetically coupling the second probe with the first probe, wherein the magnetic attraction of the magnetic coupling draws the first and second probes toward the first and second surfaces of the structure, respectively, and wherein the first and second probes cooperate by the magnetic coupling to move in a leader-follower format; and at least one x-ray detector for receiving the radiation, wherein at least one of said first probe and said second probe further comprise a display carried by the probe, communicably coupled to said at least one x-ray detector, and configured for presenting x-ray inspection images captured by said at least one x-ray detector.
