Intensity interpolation for reconstructing 3-D medical images from serial cross-sections

Reconstructing three-dimensional objects from serial cross-sections is an important operation in many medical and biological applications. Intensity interpolation makes slicing from any arbitrary angle possible and also provides accurate quantitative information for various purposes. However, the only technique available is the straightforward linear interpolation method which is technically unsound and groundless. An intensity interpolation method for two regions of interest lying on two consecutive cross-sections is proposed. Although the intensity is interpolated linearly, the corresponding points involved in interpolation are carefully selected. The experimental results show that it is superior to the straightforward method.<>
