SynchronizationType Property

Example 





Gets or sets the synchronization type used to synchronize the cells in this viewer.
Syntax
public MedicalViewerSynchronizationType SynchronizationType {get; set;}
'Declaration
 
Public Property SynchronizationType As MedicalViewerSynchronizationType
'Usage
 
Dim instance As MedicalViewer
Dim value As MedicalViewerSynchronizationType
 
instance.SynchronizationType = value
 
value = instance.SynchronizationType
public MedicalViewerSynchronizationType SynchronizationType {get; set;}
 get_SynchronizationType();
set_SynchronizationType(value);
public:
property MedicalViewerSynchronizationType SynchronizationType {
   MedicalViewerSynchronizationType get();
   void set (    MedicalViewerSynchronizationType value);
}

Property Value

The synchronization type.
Remarks
Currently, only the automatic synchronization is available.

The cells must be added to the same MedicalViewer if the user want to synchronize them together. To add the cells to the Medical Viewer, use the collection Cells.

To enable this feature, please do the following:

  1. Set the SynchronizationType to MedicalViewerSynchronizationType.Automatic.
  2. Each cell has a MedicalViewerCell.SynchronizationID property that receives a string which is used to help the toolkit identify which cells to synchronize. To synchronize two cells, pass the same value to SynchronizationID in both cells. You can pass the StudyUID to synchronize the cells from the same study.
  3. Set the image position for each frame using MedicalViewerCell.SetImagePosition method. This is required in order the Medical Viewer be able to match the series with the same image position together.
  4. Set the image orientation using MedicalViewerCell.ImageOrientation for each cell to synchronize.
