DeleteModalityLut(Int32,DicomSetImageFlags) Method
Summary
Deletes all the elements that describe the Modality LUT.
Syntax
public void DeleteModalityLut(int frameIndex,Leadtools.Dicom.DicomSetImageFlags flags)
Public Overloads Sub DeleteModalityLut( _ByVal frameIndex As Integer, _ByVal flags As Leadtools.Dicom.DicomSetImageFlags _)
public void DeleteModalityLut(int frameIndex,Leadtools.Dicom.DicomSetImageFlags flags)
public void deleteModalityLut(int frameIndex, int dicomSetImageFlags) function Leadtools.Dicom.DicomDataSet.DeleteModalityLut(Int32,DicomSetImageFlags)(frameIndex ,flags)
public:void DeleteModalityLut(int frameIndex,Leadtools.Dicom.DicomSetImageFlags flags)
Parameters
frameIndex
A zero-based index that identifies the frame number of in the dataset. If the dataset does not support Multi-frames, this parameter is ignored.
flags
determines how the modality LUT is deleted
Remarks
This method will delete all the elements defined under the "Modality LUT Module". If the DICOM dataset has a Multi-frame Functional Groups module, the Modality LUT information will be found in the Pixel Value Transformation Sequence. The Pixel Value Transformation Sequence will be under an item in either:
- (5200,9229) Shared Functional Groups Sequence
- (5200,9230) Per-frame Functional Groups Sequence
If the Pixel Value Transformation Sequence is found under the Per-frame Functional Groups Sequence, parameter uFrameIndex must be set to the correct frame number so that the proper Pixel Value Transformation Sequence is removed. If the Pixel Value Transformation Sequence is found under the Shared Functional Groups Sequence, parameter uFrameIndex is ignored. However, the DicomSetImageFlags.MfgOverwriteShared flag must be included to remove the Pixel Value Transformation Sequence. The specific elements deleted are shown below: (0028,9145) Pixel Value Transformation Sequence child elements
| Tag | Name |
| (0028,1052) | Rescale Intercept |
| (0028,1053) | Rescale Slope |
| (0028,1054) | Rescale Type |
Valid flags are DicomSetImageFlags.MfgOverwriteShared and DicomSetImageFlags.None. All other flags are ignored. For a detailed discussion on Multi-frame Functional Groups see the topic Multi-frame Functional Groups.
