Ultrasound imaging involves bouncing “ultrasonic” sound waves which are above the audible range of human hearing at the fetus and detecting the echoes that bounce back. It’s used to confirm a pregnancy, to identify the sex and number of fetuses and to detect fetal abnormalities.

How does it work? Ultrasound imaging involves bouncing “ultrasonic” sound waves which are above the audible range of human hearing at the fetus and detecting the echoes that bounce back. It’s used to confirm a pregnancy, to identify the sex and number of fetuses and to detect fetal abnormalities. During a scan, ultrasound waves are aimed at a pregnant women’s abdomen. Based on the angle of the beam and the time it takes for echoes to return, an image of body structures inside the fetus can be generated. Early in the use of fetal ultrasound, clinicians could only detect the baby’s head but gradually, with developing expertise, they could discern fine structures in the fetus https://windowtothewomb.co.uk
