IsModalityLutSequence Property

Summary

Gets or sets the Flag that indicates whether a "Modality LUT Sequence" (0028,3000) exists in the DICOM dataset or not.

Syntax

Objective-C

C++/CLI

Java

public bool IsModalityLutSequence { get; set; }

@property (nonatomic, assign) BOOL isModalityLutSequence;

public boolean getIsModalityLutSequence() 
public void setIsModalityLutSequence(boolean value)

public: 
property bool IsModalityLutSequence { 
   bool get(); 
   void set (    bool value); 
}

Property Value

true to indicates that a "Modality LUT Sequence" (0028,3000) exists in the DICOM dataset, false to indicates that a "Modality LUT Sequence" (0028,3000) does not exist in the DICOM dataset. When this value is set the properties FirstStoredPixelValueMapped, NumberOfEntries and EntryBits, LutExplanation and LutType will be valid. Otherwise, their values are undefined. Also, if this value is set the method GetModalityLutData can be called to retrieve the "LUT Data" for a "Modality LUT Sequence". Otherwise, this data will be missing.

Example

using Leadtools; 
using Leadtools.Dicom; 
 
 
public void TestSetModalityLut() 
{ 
   string dicomFileName = Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "image3.dcm"); 
   //Make sure to initialize the DICOM engine, this needs to be done only once  
   //In the whole application 
   DicomEngine.Startup(); 
   using (DicomDataSet ds = new DicomDataSet()) 
   { 
      //Load DICOM File 
      ds.Load(dicomFileName, DicomDataSetLoadFlags.None); 
      DicomModalityLutAttributes modalityLutAttributes = new DicomModalityLutAttributes(); 
      //No Modality LUT Sequence (0028,3000)  
      modalityLutAttributes.IsModalityLutSequence = false; 
      //Yes there is a rescale slope and intercept 
      modalityLutAttributes.IsRescaleSlopeIntercept = true; 
      modalityLutAttributes.RescaleIntercept = -128.0; 
      modalityLutAttributes.RescaleSlope = 1.0; 
      modalityLutAttributes.RescaleType = "UNSPECIFIED"; 
      // Delete the existing modality LUT,  
      // although we don't have to !  
      ds.DeleteModalityLut(); 
      //Set rescale slope and intercept 
      ds.SetModalityLut(modalityLutAttributes, null); 
      ds.Save(Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "MLUT.dcm"), DicomDataSetSaveFlags.None); 
   } 
   DicomEngine.Shutdown(); 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images"; 
}
