IsRescaleSlopeIntercept Property

Summary

Gets or sets the flag that indicates whether Rescale Intercept(0028,1052) and Rescale Slope(0028,1053) exist in the DICOM dataset or not.

Syntax

Objective-C

C++/CLI

Java

public bool IsRescaleSlopeIntercept { get; set; }

@property (nonatomic, assign) BOOL isRescaleSlopeIntercept;

public boolean getIsRescaleSlopeIntercept() 
public void setIsRescaleSlopeIntercept(boolean value)

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

Property Value

true to indicates Rescale Intercept(0028,1052) and Rescale Slope(0028,1053) exist in the DICOM dataset, false to indicate Rescale Intercept(0028,1052) and Rescale Slope(0028,1053) do not exist in the DICOM dataset. When this property is set the properties RescaleIntercept, RescaleSlope and RescaleType will be valid. Otherwise, their values are undefined.

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"; 
}
