From DicomObjectsWiki
To convert the COM IPicture object returned from DicomImage.Picture method to the .NET System.Drawing.Image requires the Microsoft.VisualBasic.Compatibility dll file to be referenced in your project file. That dll can be found in the .NET framework folder.
Here is the sample code to show you how to convert IPicture to System.Drawing.Image:
Dim myImage As System.Drawing.Image
myImage = Microsoft.VisualBasic.Compatibility.VB6.IPictureToImage(Viewer.CurrentImage.Picture())
myImage.Save("myImage.jpg")
