Obtain the RasterImage from the medical viewer's cells[Index]. After that, use our RotateCommand class on the image to rotate it, then assign the modified image back to the medical viewer.
The code looks like this:
===========================
RasterImage img;
img = ((MedicalViewerCell)_medicalViewer.Cells[0]).Image;
RotateCommand rotate = new RotateCommand();
rotate.Angle = 500;
rotate.Flags = RotateCommandFlags.Resample;
rotate.Run(img);
((MedicalViewerCell)_medicalViewer.Cells[0]).Image = img;
_medicalViewer.Refresh();
===========================

You have to apply the rotate command on each page. You can do that using a for loop like the following:
================
RasterImage img;
img = ((MedicalViewerCell)_medicalViewer.Cells[0]).Image;
RotateCommand rotate = new RotateCommand();
rotate.Angle = 500;
rotate.Flags = RotateCommandFlags.Resample;
for (int i = 1; i <= img.PageCount; i++)
{
   img.Page=i;
   rotate.Run(img);
}
img.Page = 1;
((MedicalViewerCell)_medicalViewer.Cells[0]).Image = img;
_medicalViewer.Refresh();
================
Note: For the rotation flags, you should use the one that best suits your requirements. For more information, please refer to our documentation.
