It gives the ultrasound technician a peek at the fetus, to identify certain key traits that can gauge how far along the pregnancy is. For instance, the presence of a 'yolk sac' is indicative of a pregnancy that is 10 weeks along or less, as that is what nourishes the baby before the placenta and umbilical cord are developed and functioning (which usually occurs at 11 weeks). There are certain traits that are only around for a certain period of time too, like a tail, the oversized head, etc. It helps them be able to more confidently say "you are 9 weeks, 1 day pregnant" as opposed to just 9 weeks. Also, the size, position, and movements of the fetus are all indicators of how developed it is.
