[Insight-users] About seed point selection in interactive way

[Xiaopeng Yang]

Hi Saraswathi,

 

Thanks very much for your help. It works for JPEG image. But in case of DICOM image, which using Hounsfield values. The example cannot calculate Hounsfield values. Do you have any idea to solve this problem? Do you know any other VTK examples which can achieve this?

 

Thanks a lot,

Xiaopeng

Hi all,

 

I made a program to visualize CT image in 2D by VTI widget. I am trying to select seed points by clicking some position in the 2D CT image interactively. Anyone knows how to program this? Does VTK has function to get the coordinates of some point in CT image? What is the name of that function?

 

Thanks,

Xiaopeng Yang
