FromDataSetToAnnContainer(DicomDataSet,DicomElement,DicomDataSet) Method

Summary

Converts all the Graphic Annotation Sequence (DICOM Annotations) stored in a Leadtools.Dicom.DicomDataSet into a LEAD AnnContainer that contains LEAD Leadtools.Annotations.Engine.AnnObject objects.

Syntax
C#
C++/CLI
public:  
   AnnContainer^ FromDataSetToAnnContainer( 
      DicomDataSet^ ds, 
      DicomElement^ graphicAnnSqItem, 
      DicomDataSet^ dsImage 
   ) 

Parameters

ds

The Leadtools.Dicom.DicomDataSet that contains the Graphic Annotation Sequence (DICOM Annotation) being converted.

graphicAnnSqItem

Pointer to an item element under the "Graphic Annotation Sequence" (0070,0001) in the "Graphic Annotation Module".

dsImage

A Leadtools.Dicom.DicomDataSet that contains an image. Only those annotations associated with the SOPInstanceUID of dsImage will be converted. All other annotations will be ignored.

Return Value

A LEAD AnnContainer that contains the LEAD AnnObject.

Remarks

This method takes Leadtools.Dicom.DicomDataSet as input, and converts all the DICOM annotations stored in the Graphic Annotation Sequence into LEAD annotations.

The LEAD annotations are returned as an AnnContainer.

Note that this method preserves any ruler calibrations, as the ruler calibration is stored in the AnnContainer.

The ds can contain annotations associated with more than one DICOM Image (i.e., SOPInstanceUID). This overload only converts those annotations associated with the SOPInstanceUID of dsImage.

All other annotations will be ignored.

Example
C#
using Leadtools; 
using Leadtools.Dicom; 
using Leadtools.Dicom.Annotations; 
using Leadtools.Annotations; 
using Leadtools.Annotations.Engine; 
 
// This example stores DICOM annotations for two different DICOM instances in the same DICOM presentation file 
// The DICOM annotations are then loaded separately for each DICOM instance 
// When running this sample, you must pass two different DICOM instances for the same PatientID 
// The following DICOM files can be used: 
//    1. C:\LEADTOOLSxx\Examples\DotNet\PACSFramework\CS\PACSDatabaseConfigurationDemo\Resources\cr1.dcm 
//    2. C:\LEADTOOLSxx\Examples\DotNet\PACSFramework\CS\PACSDatabaseConfigurationDemo\Resources\cr1.dcm
