Ultrasounds are extremely important in the process of a mom pregnancy, as these are what allow a first contact with the fetus before birth. Here we see with own eyes paternal movements of the fetus, the silhouette and position.
However, if you've ever seen a sonogram you know that is not perfectly. The traditional two-dimensional ultrasound usually hide much information do not have the precision and clarity of the actual three-dimensional vision. However, there is a mechanism that is revolutionizing the method of ultrasound.
It is 4D ultrasound or ultrasound in four dimensions. Through these dads may have a visual contact that captures the fetus as if he were looking directly, eliminating the shortcomings of the 2D view and adding a three-dimensional effect that adds to the fourth dimension: time.
4D ultrasounds introduced to real time as factor playing in them. You can see the fetus not only with their defined facial features, his mouth openings, their smiles, their stretching, etc., but also it will appreciate in real time, which gives the event that deserves realism itself.
