Potential improvement in sonar seabed mapping

Today, a significant part of the oceans remains coarsely mapped. Some specific areas like the continental shelves will require high-resolution surveys. This represents a very long and expensive task that will keep scientist busy for several decades. A way to reduce costs and time could be to improve the efficiency of current surveys. We are trying to do this by sending more signals in the water at the same time.

The Multi-beam echo sounder is recognized as one of the most efficient and reliable tool for seabed mapping. Applications range from regional mapping of the seabed for geological surveys to the inspection of man-made objects such as pipelines or ship wrecks.

Measuring the heart’s blood flow behaviour in 3D

Given that cardiovascular related diseases are the most probable cause of death globally, according to WHO, we believe that more information regarding blood behaviour can help the doctors make better diagnosis at an earlier stage. But how can you measure these properties inside the heart, behind the ribs, under the skin, without moving the patients from their bed?
