3D and 4D Sonography History and Theory

Abstract

Static 3D and real-time 4D sonography is the newest technology to help sonographers acquire images and aid in the diagnosis of pathology. Touted as a fast and efficient method of collecting needed data within a data set, the potential for increased diagnostic confidence may be a reality. Three-dimensional imaging has been evolving since the early 1970s and has now come into the clinical setting. Understanding the development of this imaging format, current theory, and terminology helps the sonographer obtain and use an optimal data set.
