Pregnancy is the culmination of many unexplained anatomical, physiological, and biochemical processes. While many aspects of pregnancy remain vague, ultrasound imaging techniques have provided a clearer understanding of many aspects of the process. This has included a more complete description of the ovulation process and implantation of the blastocyst into the endometrium. Ultrasound imaging using 3-D and 4-D capabilities has also provided a dynamic view of fetal development. A clearer and more complete description of fetal circulation is now available. In the hands of trained individuals, ultrasound techniques have captured fetal heart images revealing both normal and abnormal development. As the techniques improve, this progression of knowledge will also increase our ability to understand the entire reproductive process.
