40 // .NAME vtkSonixVideoSource - VTK interface for video input from Ultrasonix machine
41 // .SECTION Description
42 // vtkSonixVideoSource is a class for providing video input interfaces between VTK and Ultrasonix machine.
43 // The goal is to provide the ability to be able to do acquisition
44 // in various imaging modes, buffer the image/volume series being acquired
45 // and stream the frames to output.
46 // Note that the data coming out of the Sonix rp through ulterius is always RGB
47 // This class talks to Ultrasonix's Ulterius SDK for executing the tasks
48 // .SECTION Caveats
49 // You must call the ReleaseSystemResources() method before the application
50 // exits. Otherwise the application might hang while trying to exit.
51 // .SECTION Usage
52 // sonixGrabber->SetSonixIP("130.15.7.212");
53 // sonixGrabber->SetImagingMode(0);
54 // sonixGrabber->SetAcquisitionDataType(0x00000004);
55 // sonixGrabber->Record();
56 // imageviewer->SetInput(sonixGrabber->GetOutput());
57 // See SonixVideoSourceTest.cxx for more details
