4D ultrasound machine
By updating 3d ultrasound images in rapid succession, sonographers can also create 4d ultrasound pictures. In the 4d ultrasound, the fourth dimension, time, adds movement and creates the most realistic representation of all.
In some cases, 3d and 4d ultrasound pictures may reveal abnormalities not readily seen using 2d ultrasound. For expectant mothers and family members, the ability to see realistic images of an unborn baby in the uterus can be rewarding and heartwarming although the medical community in general cautions against performing ultrasound tests solely for this purpose.
