[ITK] [ITK-users] Float dicom images

[David Clunie]

We (DICOM) have only recently added support for floating point
pixel data in DICOM (Sup 172), so I don't know if any of the
toolkits used by ITK support it yet.

I know dcmtk will, hopefully soon, but I can't speak for GDCM.

I have some samples at:

   https://www.dropbox.com/sh/n4iqdjbhmwljx5e/AABllea-Muk0C2oo576nm_Mua?dl=0

if you want to try them; not perfect yet, but they have the float pixel
data payload.

I am assuming that you actually want to write floating point pixels,
rather than integer quantized pixels with a floating point scaling
factor.
