Three dimensional CT reconstruction: a comparison between 2D, 3D CT and original anatomical structures.

Conventional two dimensional computed tomography has provided significant advancement in clinical diagnosis with information on cross-sectional anatomy of various parts of the body. However, three dimensional representations are not directly available. This is now made possible by recent development of CAD software and CT equipments and technique such as multiplanar reformation capable of providing 3D reconstruction using 2D CT data. This article evaluates the accuracy of measurements and dimensions in 3D CT reconstruction.
