A new efficient method for 3D registration using human brain atlases

In this article a new efficient method in deformable brain atlases is proposed. To achieve this goal we use the composition of two applications, an affine transformation and other one. In this second application we have used three different approaches. One approach that has been used and two new approaches. We use a set of points to be identified both in brain atlas and in patient's brain for registration. The three approach present an advantage: the mathematical solution obtained makes it to be very fast, almost immediate. Several results have been obtained and they have been classified as very satisfactory by the neurosurgeons that have tested our system.
