[Insight-users] getting an flat picture from dicom volume

[Luis Ibanez]

Hi Hadi,

You may want to use the ProjectionFilters:

See the derived classes of:
http://www.itk.org/Insight/Doxygen/html/classitk_1_1ProjectionImageFilter.html

A common choice is to use the

      itkMaximumProjectionImageFilter.h


Please note that these filters will compute projections
for lines that are parallel to the image axis.

If you have a line that is not parallel then you
should consider the methods used for Digitally Reconstructed
Radiographs (DRR) illustrated in


   InsightApplications/
       IntensityBased2D3DRegistration/
                 GenerateProjection.cxx


That being said...
If you are generating this flat image for the sole
purpose of visualization, then you will have a lot
more flexibility by doing Volume Rendering with VTK.



    Regards,



        Luis
