Development

Create Dataset

• Use data sent by James Barabas (MIT)
• Convert them in several 3D Volumes (256*256*256), and fill with 0 on Matlab
• Save data as raw volumes

Simulate scanner sending data to Slicer

• Use ImagerClient from OpenIGTLink to send volumes
• Change values to match with 3D Volumes created (values are hardcoded for now. Need a parser ?)

Create 4D Ultrasound Module

• Create module to create TimeSeries
• Modified vtkMRMLNode to automatically saved any attributes (available on branch)
• Used this modification to save TimeSerie ID to be able to load them and recreate TimeSerie
• Need to add timestamp to know which node is the first, second, third, .... in the TimeSerie when reconstructing it

Tips

• Orientation of EM and Optical system are different because coordinate system are different (not possible to "fix it"), so I created a model flipped, and use it to display EM tracker
• Aurora configuration (from IGSTK):

 communication->SetBaudRate(SerialCommunication::BaudRate9600);                   // Baud: 9600
 communication->SetDataBits(SerialCommunication::DataBits8);                      // DataBits: 8
 communication->SetParity(SerialCommunication::NoParity);                         // Parity: 0
 communication->SetStopBits(SerialCommunication::StopBits1);                      // StopBits: 1
 communication->SetHardwareHandshake(SerialCommunication::HandshakeOff);          // HandShake: 0
