INVERSE - output after inversion is in P-Values - shall be used if Photometric Interpretation (0028,0004) is MONOCHROME1. See C.8.11.3.1.2 for further explanation.
(0028,2110)Lossy Image Compression1 Specifies whether an Image has undergone lossy compression. Enumerated Values: 00 = Image has NOT been subjected to lossy compression. 01 = Image has been subjected to lossy compression. See C.7.6.1.1.5 for further explanation.
(0028,2112)Lossy Image Compression Ratio1C See C.7.6.1.1.5 for further explanation. Required if Lossy Compression has been performed on the Image. Derivation Description (0008,2111) 3 A text description of how this image was derived. See C.8.11.3.1.4 for further explanation.
(0018,1400)Acquisition Device Processing Description3 Indicates any visual processing performed on the images prior to exchange. See C.8.11.3.1.3 for further explanation.
(0018,1401)Acquisition Device Processing Code3 Code representing the device-specific processing associated with the image (e.g. Organ Filtering code) Note: This Code is manufacturer specific but provides useful annotation information to the knowledgeable observer.
(0020,0020)Patient Orientation1 Patient direction of the rows and columns of the image. See C.7.6.1.1.1 for further explanation.
(0050,0004)Calibration Image3 Indicates whether a reference object (phantom) of known size is present in the image and was used for calibration. Enumerated Values: YES NO Device is identified using the Device module. See C.7.6.12 for further explanation.
(0028,0301)Burned In Annotation1 Indicates whether or not image contains sufficient burned in annotation to identify the patient and date the image was acquired. Enumerated Values: YES NO
(0028,3010)VOI LUT Sequence1C Defines a sequence of VOI LUTs. See C.8.11.3.1.5 for further explanation. Required if Presentation Intent Type (0008,0068) is FOR PRESENTATION and Window Center (0028,1050) is not present. May also be present if Window Center (0028,1050) is present.
