Great, now instead of simply googling my symptoms, I can also attempt to read an ultrasound. Image search maybe?

You can also use ultrasounds to see your body composition. As in how much of this body part is fat vs muscle.

Although I think 3d imaging will work in a more convenient manner for that purpose, and it will only get cheaper, so I doubt it will become that popular for that purpose if it was made cheap.
