You can give it the same tests the human radiologists take in school.

They do take tests, don't they?

They don't all score 100% every time, do they?

The point here is that the radiologists has a concept of knowing which light patterns are sensible to draw conclusions from and which not, because the radiologist has a concept of real world 3D objects.

Sure. It's just not a valid point. Even if it's valid today, it won't be by next week.
