Streaming Delay between tracking and US video data is too long

I performed temporal calibration (i.e. synchronize tracking and video streams) for the probe but the delay is very important (1.2 seconds approximately). This delay impact the real-time visualization of the ultrasound image in the 3D view. I also had an error from the PLUS Server when I tried to acquire a 3D volume because the tracking stream delay is too important as compared with the video streaming.

This could be because we are tracking the stylus and probe at the same time (which we know decrease the frame rate) or it could be also related to the lags happening on Slicer after loading the 3D model via OpenIGTLink. If the problem comes from the way the Stealthstation send the tracking data it might be very tricky to solve.

@RolandGuichard to meet with @RemiDelaunay to play with it on the mockOR. Sometime early next week.

changed title from Streaming Delay between tracking and video data is too long to Streaming Delay between tracking and {+US +}video data is too long

• Check the temporal calibration of the StealthStation
• Go through the calibration process
• Check the synchronisation
