How does ultrasound figure the scan date?

Answer by  Melissa101010 (4405)

Usually the ultrasound technician takes measurements and scans of the object that they are scanning and that usually figures the scan date for the technician. Also, if multiple scans are done then size can help determine date.

Ultrasounds help technicians determine the pregnancy date by measuring the size of the baby's legs, arms and torso. With this information the doctors and tech's are able to estimate the timing of your pregnancy and provide you with a more accurate due date. It takes skill and knowledge in order to achieve this.
