Ultra-small sensors already exist for some time. The problem: The probes are either sent through the blood vessels or gastrointestinal investigations through the esophagus into the body and has had only one viewing direction. So there was always a rather large blind spot that could not be illuminated in major investigations.

Conventional ultrasound examinations from the outside, which will penetrate deep into the interior of the body to provide physicians with an overview on the state to procure organs, are virtually impossible because the required higher sound track to the detriment of image resolution. Therefore, ultrasound is now used primarily for pregnancy diagnosis. For deeper investigation, however, people take up much more expensive tomography.

With the new probe was developed by researchers at the University of Albuquerque in the U.S. state of New Mexico, are the “tunnel vision problems” of the past. Within a short time, the probe may, if it is swallowed as a pill, for example, more accurately provide a picture of the stomach or digestive tract. In the future, the researchers will see, however, the probe deep in the brain, to explore where the bloodstream and thereby prevent strokes or aneurysms.
