In the past, farmers had to go to the city far away if they want get medical-treatment,how hard and inconvenient they are. Now the portable ultrasound machine realized the function of B-ultrasound in countryside and people can get treatment at home. Portable ultrasound machine benefit both farmers and astronauts,which can be taken into the space as auxiliary medical care for astronaut.
