3D - 4D Ultrasound in Obstetrics and Gynecology

Three dimensional (3D) ultrasound (USG) and 4D i.e. real time 3D are a natural development of the imaging technology and were first demonstrated nearly 15 years ago, but are becoming a clinical reality only now. Methods for 3D reconstruction of CT and MRI images have achieved an advanced state of development. 3D applications in ultrasound have lagged behind CT and MRI, because ultrasound data is much more difficult to render in 3D. Only in the past few years has the computing power of ultrasound equipment reached a level adequate enough for the complex signal processing tasks needed to render ultrasound data in three dimensions. The clinical application of 3D ultrasound is likely to advance rapidly, as improved 3D rendering technology becomes more widely available
