[Insight-users] Segmentation of Breast Images (Images availableonly without contast agent)

[Julien Jomier]

Hi Neha,

This is a known issue with ITK 1.6 amd VTK 4.2 due to duplicate symbols.
Can you use ITK 1.8 and InsightApplications 1.8 instead?
Your CMake options are good.

Let us know if you still have this issue with the 1.8 version,

Julien

Hello,
I am trying to compile ITK 1.6 applications.  I downloaded VTK 4.2
Soucecode, compiled it using USE_HYBRID_OPTION - ON and ANSI_STD_LIB - ON,
and USE_PATENTED_CLASS - ON.  

After that, trying to compile ITK 1.6 applications with USE_VTK - on gave me
attached error messages.  (USE_VTK_RENDERING and USE_PATENTED_CLASS - ON
too)
Do I need to set these 2 options OFF? Any suggestions?

Thanks,
Neha

HI Neha,

You can find Breat images at

www.mypacs.net

you can create an account for free and
download real datasets.

Look for the title "Shared Cases" and
click in "Breast".

You may want try the advanced Mathematical Morphology
methods such as: FillHole and GrindPeak.

Taking an input imag, applying one of these filter and
then subtracting from the original may enhance spiculations
and calcificaitions. You will have to fine tune the structuring
element for matching the relative size of calcifications in your
image.
