TIOParams.DICOM_AdjustedValueMin

Declaration

property DICOM_AdjustedValueMin: Double;
property DICOM_AdjustedValueMax: Double;
property DICOM_AdjustedValueMode: TIEDicomRange;

Description

When the pixel values of a DICOM image have been adjusted during loading (DICOM_RangeAdjusted = True), these return the original values (after applying Rescale Slope and Rescale Intercept, e.g. Hounsfield units) that are represented by the minimum (0) and maximum (255 or 65535) pixel values.
They are used by DICOM_PixelToValue, and to write Rescale Slope and Rescale Intercept tags when saving, so that pixel values map back to their original units.
The values are only valid if DICOM_AdjustedValueMax <> DICOM_AdjustedValueMin (DICOM_AdjustedValueMax < DICOM_AdjustedValueMin if the pixel values have been inverted, e.g. MONOCHROME1 images).
DICOM_AdjustedValueMode is the DICOM_Range that the values relate to. Rescale tags are only written when saving if it is iedrAdjust (e.g. it is iedrSetBlackWhite if the image was loaded with iedrSetBlackWhite and then StretchValues was called without updating the values).
