This approach successfully produced 3-D images of the fetus which were nevertheless inferior to that produced on convenional 2-D scanners. The images obtained were processed on elaborate computer systems (see picture with description below). Baba, with Kazuo Satoh and Shoichi Sakamoto at the Saitama Medical Center described the improved equipments in 1989 in which they used a traditional real-time convex array probe from an Aloka SSD280 scanner mounted on the position-sensing arm of a static compound scanner (Aloka M8U-10C). Their setup was reported in the Acta Obstetrica et Gynaecologica Japonica. Kazunori Baba at the Institute of Medical Electronics, University of Tokyo, Japan, first reported on a 3-D ultrasound system in 1984 and succeeded in obtaining 3-D fetal images by processing the raw 2-D images on a mini-computer in 1986. The principle has always been to stack successive parallel image sections together with their positional information into a computer. Of the probe can be accurately determined. Real-time scanner probes mounted on articulated arms were often employed where positions Other work came from the domain of cardiologists where initial efforts were directed to acertaining the volume of cardiacĬhambers. Some basic computer algorithms came from the group at Stanford ( JF Brinkley, WD McCallum and others) and also from the Holm group at Gentofte, Denmark. Three-dimensional visualization began to appear in theĮarly 1980's. With improvements in ultrasonic and computer technology, work on In the early 1970s, who had developed an elaborate Multiplanar scanner in 1973, under the Sonicaid Ltd®. Investigators, including Tom Brown in Glasgow Visualization of the fetus in 3-D has always been on the minds of many Three-dimensional ultrasound comes of age Ultrasound in Obstetrics and Gynecology, reproduced separately here. This is part of the full article A short History of the developments of 3D ultrasound in obstetric imagingĪpplications for 3D ultrasound obstetric imaging are also being developed, such as determining gestational sac location if there is a question of interstitial ectopic pregnancy.History of the developments of 3-D Ultrasound in Obstetrics and GynecologyĪ short History of the development of 3-D Ultrasound in Obstetrics and Gynecology Dr. Uses of 3D imaging for the uterine adnexa is currently being developed and may have an application in delineating tubal abnormalities, such as hydrosalpinx. This technique may be found in detail in reference 2. The "Z-technique" is used in many institutions that practice 3D gynaecologic ultrasound. The quality of the 3D images depends on the quality of the 2D images. uterine fibroids (particularly % submucosal component)ģD gynaecologic imaging can be performed with either the transabdominal or endovaginal approach, but the endovaginal approach results in better quality images.evaluation of intrauterine contraceptive device (IUCD) location.evaluation of uterine shape abnormalities (e.g., Mullerian duct abnormalities).This format has been found to be useful for: 3D ultrasound in gynaecologic imagingģD ultrasound has found a useful application in imaging the coronal plane of the uterus. The technique was developed for problem-solving (particularly in obstetric/gynaecologic exams) and to potentially reduce the operator dependence of ultrasound imaging. The 3D image can then be reviewed retrospectively. Three-dimensional (3D) ultrasound is a technique that converts standard 2D grayscale ultrasound images into a volumetric dataset.
