The 3D scan is a method used to perceive the objects as they actually look. For this system a 3D scanner is used. It obtains all in rank about the object and stores it. This stored information is then used to model a alike object. This is used in many recent applications like the simulation in movies and games. It is used in the medical field also. A 3D scan helps to design false body parts in area of deceased part. 3D scanner can take images of various things and based on the margins costs are constant. Better arresting of picture will price more than a moderate quality. 3D scan have its advantages and limitations. Its limitations would be the difficulty to check a glittery surface. But some modifications on the surface can make scanning possible. 3D scan is also made for the fetus. It helps us to see the reside movements of the child in the womb and also can see its different parts of the body. These scans are helpful in shaping any deformations in the baby at a very early stage. It is likely to get dual black and white or colour images of the object or the foetus.
