3d and 4d Sonographic Assessment of Multiples

Three-dimensional sonography (3D US) provides completely new modalities of sonographic scanning including coronar section imaging, three-dimensional reconstruction, volumetric calculations and angio-mode. Improved visualization rate, depiction of spatial relationship, "sculpture like" plastic imaging and volume measurement are the main benefits of new technology. Acceleration in scanning and rendering capabilities of the last generation of three-dimensional machines provided three-dimensional imaging almost in real-time. Stated another way/ surface rendered and multi-planar images can be observed in near real-time. This imaging technique is characterized as four-dimensional sonography (4D US). If one performs 4D US, accomplishing of three-dimensional image reconstruction is less time consuming because simultaneous with probe movement adequate image is displayed. Therefore, 4D US is more suitable and acceptable for routine prenatal care than 3D US.
