[Insight-users] extracting a circular interest region

[Luis Ibanez]

Hi Zhihong,

You may want to try creating a binary image with a circular
mask and then using it with the MaskImageFilter.

In order to create the circular maks you can use the 
EllipsoidSpatialObject and the SpatialObjectToImageFilter.

You may find useful to look at the example:

    Insight/Examples/Registration/
       ModelToImageRegistration1.cxx



   Regards,


       Luis
