Engineers in Britain have developed an ultrasound scanner that costs under 40 pounds to make and could improve prenatal care in parts of the developing world where this technology is out of reach. The device, if it gets commercial backing, would enter a market where hospital-based ultrasound scanners cost anything between 20,000 pounds and 100,000 pounds ($32,100 to $160,600) and low-cost, portable devices sell for around 4,500 pounds each.
