| − | | |
| − | To the right the Ultrasound Server is retrieving images based on the position of the scanner.
| |
| − | The computer's server software supports an interface to translate the scanning planes and to retrieve and send images from the scanner.
| |
| − | | |
| − | Then the data is transferred over the network using the openIGT link, the network protocol of Slicer.
| |
| − | | |
| − | Finally 3D Slicer visualizes the data and sends tracking commands back over the link to update the viewing plane.

| |
| − | This is the region that has to be designed by the developers of the scanner.

| − | == Data Transfer ==
| |
| − | There are two data transfers involved in this process, ''Image Transfers'' from the scanner to slicer and ''command transfers'' into the revers direction.

| − | === Image Transfers === | |
| − | To transfer an image from a server to 3D Slicer the following objects have to considered:
| |
| − | #Open connection to 3D Slicer
| |
| − | #Data Creation
| |
| − | ##Create ImageData buffer on server
| |
| − | ##Create MRML Node holding a ImageData in Slicer connected to the ImageData on the server
| |
| − | #Data Transfer
| |
| − | ##Fill ImageData buffer on Server with US Data
| |
| − | ##Send Data over Link
| |
| − | | |
| − | By now the MRML node's image data is updated and ready to visualize.
| |
| − | | |
| − | === Command Transfer ===
| |
| − | Tracking commands are sent using the command structure supported by slicer's openIGT Link
| |
| − | | |
| − | == Data Visualization ==
| |
| − | To Transfer 3D images from the scanner to Slicer we make use of openIGT Link
