3-D medical scans have moved beyond the novelty stage and are now being used to save lives helping heart surgeons in the operating room.
The technology helps doctors scan the heart and look at it in the front, back and sides.
By allowing surgeons to see these type of images, they can plan the operation the day before to their advantage.
The 3-D ultrasound also measures the strength of the heartbeat. If it weakens, they can change or adjust medication.
Duke Medical Center in North Carolina and Children's Hospital in Boston also have this technology.
