| Summary | 0008538: Incorrect loading of DICOM MONOCHROME1 images with Pixel Padding Value != 2^bits stored-1 | ||||
| Description | I 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. | ||||
