I don't know of any method that would allow you to see in side.
There maybe a device that can measure wall thickness but you'd need to know what they should be in the first place.
I've never seen a bike that rusty and I once found a pre WW1 hercules in a drainage pit in a London underground depot.
And yes it did still ride, after a bit of a talking to.
You might be better off starting a new thread on frame repairs to get a bit more detailed response, i'm sure some one must have had a frame repaired.
