I mean, it relates, but is that really what I want to see as a visitor? It's a skeleton. Not appealing, at least to me. I think you want something that gives a sense of security and warmth, not something internal and (in my opinion) disgusting (I'm not a big internal medicine guy - all that stuff makes me squeamish).
While it's true that images need to relate, it should also make the visitor feel good. Especially in a doctor setting, you want the visitor to feel comfortable, relaxed, and secure. Maybe some warm colors (a light tan) w/ just a smiling model (like, not a scantily-clad model, just a model for a photograph) in a doctor's suit would do the trick.
Unless you meant that as a picture for an article - then that would depend on the article.
