AI Improving Biomedical Imaging

It is notable how modern AI is doing best in 'vision' spaces.    As opposed to what I would call conversational interaction and process logic.   Not what we would have expected in the earlier applications of AI.  Is this because the training data is more available and concise, or because the underlying deep learning models are closer to the underlying human intelligence?   Or both?

Artificial intelligence improves biomedical imaging in TechXplore
by Fabio Bergamin, ETH Zurich

ETH researchers use artificial intelligence to improve quality of images recorded by a relatively new biomedical imaging method. This paves the way towards more accurate diagnosis and cost-effective devices.

Scientists at ETH Zurich and the University of Zurich have used machine learning methods to improve optoacoustic imaging. This relatively young medical imaging technique can be used for applications such as visualizing blood vessels, studying brain activity, characterizing skin lesions and diagnosing breast cancer. However, quality of the rendered images is very dependent on the number and distribution of sensors used by the device: the more of them, the better the image quality. The new approach developed by the ETH researchers allows for substantial reduction of the number of sensors without giving up on the resulting image quality. This makes it possible to reduce the device cost, increase imaging speed or improve diagnosis. .... "
