The 3D scan is a method used to see the objects as they actually look. For this system a 3D scanner is used. It obtains all in rank about the thing and stores it. This stored information is then used to model a similar object. This is used in many recent applications like the simulation in movies and games. It is used in the remedial field also. A 3D scan helps to design false body parts in region of deceased part. 3D scanner can take images of vivid things and based on the limitations costs are fixed. Better capturing of picture will price more than a moderate quality. 3D scan have its advantages and limitations. Its limitations would be the hard to examine a glittery surface. But some modifications on the surface can make scanning possible. 3D scan is also make for the fetus. It helps us to see the survive movements of the baby in the womb and also can see its various parts of the body. These scans are aid in determining any deformations in the baby at a very premature stage. It is possible to get two black and white or colour images of the thing or the foetus.
