Module Description

This module allows you to change the model of a tracked tool for image-guided therapy. Used with the OpenIGTLink IF Module, a vtkPolyData model can be assigned to a transformation from the tracking system. This module has PolyData models for a needle and a probe. The user can also choose to toggle on/off (i) the target (tip) location and (ii) the tool projection. It is assumed that the projection of the tool is in the negative z-direction.

Usage

Use Cases, Examples

This module is especially appropriate for these use cases:

  • Use Case 1: This is intended for IGT applications where virtual representation of the surgical tool is needed for interaction with an image. Currently, this module is limited to a single tool but plans are in place to expand it to multiple tools.

Examples of the module in use:

  • Example 1 -- To be completed at a later date.

Quick Tour of Features and Use

  • Tool Properties Panel:
    • Probe Transform: Select the MRML node that contains the probe transform being served up from the tracking system via the OpenIGTLink IF Module.
    • Tool Type List: Select the tool type being tracked. Currently only three types are available: the OpenIGTLink Default, Needle and a Pointer Probe. It is easy to added other models by adding functions to the Logic code.
    • Enable Tool PolyDdata Checkbox: Toggle the tool on and off.
    • Show Axes Checkbox: Toggle the tool axes on and off.
    • Show Tool Projection: Toggle the projection line on and off.
    • Set Projection Length Slider: Control the length of the projection line. 250mm is the maximum (Is this reasonable?).
    • Set Projection Diamater Slider: Control the size of the radius of the projection line. 10mm is the maximum.
    • Show Tool Tip Location Checkbox: Toggle the tool tip sphere on and off.
    • Set Tool Tip Diameter Slider: Control the size of the sphere at the tool tip location. 10mm is the maximum.

Development

Notes from the Developer(s)

Dependencies

None are needed, but you will need a transform either from OpenIGTLink or somewhere else. If you just want to test the module. Create a new transform using the Transforms Module and leave as the identity and assign that transform as the Probe Transform in this module.
