Tracking

Tracked ultrasound communication will use the TDATA message.

Use 1 bit of the Reserved byte to indicate valid/invalid status

Use metadata attributes for tool status information:

Attributes

<ToolStatus>
  <Tool Id=”Reference” Status=”WARNING” Description=”Marker 1 on tool X is damaged” />
</ToolStatus>
  • Status
    • "OK"
    • "WARNING"
    • "ERROR"
  • Description: human-readable string
