Three-dimensional ultrasound imaging.

چکیده
Two-dimensional viewing of three-dimensional anatomy by conventional ultrasound limits our ability to quantify and visualize a number of diseases and is partly responsible for the reported variability in diagnosis. Over the past two decades, many investigators have addressed this limitation by developing three-dimensional imaging techniques, including three-dimensional ultrasound imaging. In this paper we describe the development of a number of three-dimensional ultrasound imaging systems that make use of B mode, color Doppler, and power Doppler. In these systems, the conventional ultrasound transducer is scanned mechanically or by a freehand technique. The ultrasound images are digitized and then reconstructed into a three-dimensional volume, which can be viewed and manipulated interactively by the diagnostician with a variety of image-rendering techniques. These developments as well as future trends are discussed with regard to their applications and limitations.

The Role of Three Dimensional Transvaginal Ultrasound in Detection of Intrauterine Device Displacement in Post Caesarean Section: A Case Report
Intrauterine Devices (IUDs) are used as an efficient and inexpensive method of contracep¬tion. Contraceptive efficacy depends on the intrauterine location of IUD and intrauterine displacement of the IUD leads to decreased contraceptive efficacy. Expulsion of IUD and its penetration into myometrium is one of the complications of IUD. In cases where IUDs are not detected by ultrasound method, in ...

OBJECTIVE To present the appearance of the fetal akinesia deformation sequence by three-dimensional ultrasonography after four-dimensional ultrasonographic scanning. METHODS Three-dimensional surface-rendering images were used to show the fixed postural abnormalities of the fetal extremities and body. Four-dimensional ultrasonography was used to show that the postural abnormalities were fixed...
