Trial begins of AI scan that could reduce risk of stillbirth and other conditions

Although the placenta can be visualised using ultrasound, measuring it, and all the tiny blood vessels supplying it, is extremely time consuming, making this impractical for routine early pregnancy screening. So the University of Oxford has used machine learning to develop a tool, trained on thousands of ultrasound images where the placenta has been painstakingly marked out by hand, to automate the recognition process.
