How to normalize the intensity?

Support
1

Hello, everyone!

I am working with prostate adc maps and trying to measure adc value for prostate tumors in order to demonstrate that there is a correlation between adc value and Gleason score.

I understood that i must first normalize the intensity of the images. The problem is that i don’t really know how to do that.

I appreciate any information you may have.

@Floren The way I typically do it, not sure if it’s the best way

  1. module finder
  2. simple filter
  3. rescaleIntensityImageFilter
    I suggest you make a clone of your volume first, and then output into a different volume so you still have a copy of the original.

Depending what you would like to normalize it to, the ShiftScaleImageFilter could also be a good option (src: Is it possible to rescale intensity of a volume?)

If you would like to normalize to something like the Hounsfield Unit (HU), then Grey values (GV) to HU units conversion provides a more advanced approach.
