Following are the technological advancements that are expected to shape the ultrasonic devices industry in the coming years.
3-D/4-D ultrasound technologies. Availability of better visualization owing to advancements in 3-D and 4-D ultrasound technologies has helped gynecologists to determine congenital birth defects. The golden-colored images offered by 3-D/4-D ultrasound aid in detecting defects distinctly as compared to grey-colored images delivered by 2-D ultrasound systems. So, congenital birth defects such as spina bifida, cleft palate, and others are easy to detect and conduct diagnostic procedures. In addition, cardiologists benefit from these technologies due to availability of real-time data and quantitative diagnostic information.
Different tools are available in 3-D technologies, such as multi-planar display, which helps in rendering orthogonal views for fetal brain and cavities. In addition, it also helps gynecologists to view baby’s face, hands, and other features through surface rendering and determine genetic syndromes. Maximum intensity projection is another tool that assists clinicians to view structures of bone, including skull or vertebra more distinctively. Thick slice scanning helps visualize toes, fingers and anomalies like cleft palate better. 3-D inversion mode is helpful in examining fluid-filled structures, including brain ventricles or fetal stomach.
3-D ultrasound helps in improving precision in fetal weight estimation by measuring fractional thigh volume. This, in turn, helps in assessment of prenatal nutritional status by assessment of soft tissues of fetal limbs. Wesley Lee, co-director, Texas Children’s Fetal Center, Texas Children’s Hospital Pavilion for Women, Houston, Texas, is conducting a research based on this method. Emphasizing the role of 3-D ultrasound in assessment of fetal limbs, he said, “We have to develop new ways and novel approaches for determining which babies are truly malnourished. That’s why we are using fractional limb volume as part of the fetal weight estimation procedure to assess the fetus before delivery.”
The examination of the moving heart and obtaining dynamic multi-planar views of the heart is possible with the help of spatial temporal image correlation (STIC) technique, which uses 4-D ultrasound. Benefits of 3-D and 4-D ultrasound technologies, such as practical, easy-to-use, safe, and shorter exam time give ultrasound a new life and increased relevance in medical imaging.
