“Images from inside the body? It can be done with tiny cameras which the patient has to swallow. In the past there was no way of controlling the device as it passed through the body. Now it can be steered and stopped where desired, and even deliver images of the esophagus.”
wow.. it’s like ‘Fantastic Voyage’ come to life!
(except for the miniature people part..)
