Summary0008538: Incorrect loading of DICOM MONOCHROME1 images with Pixel Padding Value != 2^bits stored-1
DescriptionI tried to load a DICOM MONOCHROME1 image (MG), see relevant DICOM data in additional information.

The Largest Image Pixel Value is 32767 and Pixel Padding Value 32767 (recommended to be 2^16-1 = 65535) but not mandatory.

In gdcm::PixelReadConvert::ConvertFixGreyLevels() always pixels are converted in the form:

value = 65535 - value

which results in pixels above the 5571 - 32767 range for this image.

In my opinion, in this case it should be

value = 32767 - value

which gives the correct values.
