Oblique Multi-Planar Reformation Using Viewport Translation Technique on Visualization Toolkit Library

In medical applications, image processing software becomes widely used for visualization, planning, and diagnosis. In this paper, we develop a simple model for oblique reconstruction by a viewport translation technique with the Visualization Toolkit Library (VTK). This technique allows a user to analyze inner anatomic structures in any oblique slice. The user can adjust the oblique plane of interest by rotating it up to 180 degrees as desired. With the concept of the proposed technique, we generate the oblique multi-planar reformation by rotating only the axial plane of interest and then generating the new oblique axial, sagittal and coronal views automatically. The proposed technique was implemented on Java and VTK. Using medical CT data, the experimental results show that our proposed process can display the oblique views successfully with easy adjustment.
