Hi,
I want to try image-guided surgery using slicer developed module.
The main Notes (displayed in data module) include :
-
Ultrasound (
vtkMRMLVolumeNode
, real time transmission by openigtlink module through a image grabber connected with ultrasound machine) -
ImageToProbe
(constant linear transform),ProbeToTracker
(real time linear transform acquired by NDI and transmitted by openigt module ) Their data type are bothvtkMRMLLinearTransformNode
.
And with the help of openigtlink module, the hierarchy in Data module likes:
|--Ultrasound
|--ImageToProbe
|--ProbeToTracker
In oder to realize the function of image-guieded surgery, I need to transform Images (Ultrasound) from image coordinate system to tracker coordinate system. so I choose to adjust hierarchy ( draging nodes):
|--ProbeToTracker
|------ImageToProbe (success)
|----------Ultrasound (fail)
I have tried many times, but failed to drag "ultrasound "node to the lower level of ImageToProbe
node.
More details about my system configuration are:
