How to get the intensity values at different pixel locations in DICOM image?

1

Hello,

I am using ITK and VTK for liver segmentation purpose. But my segmentation algorithm needs seed point which I have to select from DICOM images. Firstly, I was using 3D slicer to take seed point positions. But Now I have to select it directly from dicom viewer using VTK.
So how can I get a seed point position by just selecting randomly on dicom image? Also how to check intensities at different pixel locations ?

Kindly help me with some information.

Those is more of VTK questions than ITK ones. Perhaps look at this thread, if that does not help you please ask further questions on VTK forum.
