Scaling HU values after image loading


(Dan) #1

Hello. Thank you for the excellent work on ITK.

Is there a set of built-in functions for scaling the HU values read from the DICOM images? E.g. are there bone, lung, etc defaults? Are there methods for balancing the data?

Thank you.

Hello @danelliottster,

I think what you are looking for is the IntensityWindowingImageFilter. There are no presets for bone, lung, etc. . As you are working with CT and HU, you can use the known values for specific anatomical structures to create these presets for the window minimum and maximum.
