SaveJson(DicomDataSet,string,DicomDataSetSaveJsonFlags) Method

Summary

Saves the contents of the DICOM data set in DICOM (JavaScript Object Notation)JSON model format (specified in PS3.18) to the specified output file.

Syntax

C++

[ExtensionAttribute()] 
public static void SaveJson( 
   DicomDataSet ds, 
   string fileName, 
   DicomDataSetSaveJsonFlags jsonFlags 
)

<ExtensionAttribute()> 
Public Overloads Shared Sub SaveJson( _ 
   ByVal ds As Leadtools.Dicom.DicomDataSet, _ 
   ByVal fileName As String, _ 
   ByVal jsonFlags As Leadtools.Dicom.Common.Extensions.DicomDataSetSaveJsonFlags _ 
)

[ExtensionAttribute()] 
public: 
static void SaveJson(  
   Leadtools.Dicom.DicomDataSet^ ds, 
   String^ fileName, 
   Leadtools.Dicom.Common.Extensions.DicomDataSetSaveJsonFlags jsonFlags 
)

Parameters

ds
The contents of this data set to be saved

fileName
The name of the output JSON file.

jsonFlags
Flags that affect how binary data and other information is saved in the JSON output file.

Remarks

Use this method to export a DicomDataSet as human-readable JSON file. By default, all binary data is using BulkDataUri with dummy URIs, but this behavior can be modified by passing appropriate DicomDataSetSaveJsonFlags

The output JSON format is the DICOM JSON Model defined in the DICOM specification in PS3.18.F.

Note: When saving the pixel data of multi-page compressed files to JSON, only the first frame is saved. This is because of the restriction specified in PS3.18.F.2.7 that states "There is a single InlineBinary value representing the entire Value Field, and not one per Value".

Example

This example loads a sample DICOM file, and saves the contents as a JSON file, where the binary data is exported as InlineBinary base64
