3-D ultrasound images of fetus seen in real time.
Engineering researchers at Duke University in Durham, N.C., modified the commercial version of a real-time, 3-D ultrasound scanner to produce an even more realistic perception of depth.
The Duke researchers created an updated version of the image-viewing software found on clinical ultrasound scanners, making it possible to achieve a stereo display without additional hardware. Images seem to pop out of the screen when viewed with special glasses.
The new imaging capability can improve the early diagnosis of certain kinds of birth defects of the face and skull and improve surgeons' depth perception during ultrasound-guided medical procedures, including tumor biopsies and robot-assisted surgeries done through tiny keyhole incisions.
After first demonstrating the new capability by generating stereo ultrasound images of a small metal cage, they advanced to ultrasound images in living animals and have since recorded ultrasound images of a model human fetus that is traditionally used in the testing of fetal ultrasound imaging devices.
