Principles of Threedimensional Ultrasound in Gynecology and Obstetrics
In the past ten years, development of ultrasound diagnostic technology has been very fast, especially in the field of three- and four-dimensional ultrasound. The purpose of this article is to familiarise the reader with the physical background and possible applications of these technologies in gynecology and obstetrics. Different display modes of information (volumes) acquired using a three-dimensional ultrasound probe are described. Software integrated in three-dimensional ultrasound machines, which offer the possibility of measurement and analysis of acquired volumes are presented. The results of clinical studies which evaluated the usefulness of three-dimensional ultrasound at solving different problems in gynecology and obstetrics are also reported.
