| − | = The Intelligent Systems of Medicine Laboratory (ISML) mission is to work towards improving clinical outcomes through appropriate use of technology. We are interested in biomechanics (both engineering biomechanics and sport biomechanics), biomedical engineering, computer integrated surgery, medical robotics and related fields. We run exciting research projects in these areas, generously funded by The Australian Research Council and other agencies.

| − | We intend to contribute to Na-MIC by providing algorithms for computing the intra-operative brain deformations for image-guided neurosurgery. We treat the brain shift as a continuum mechanics problem involving finite deformations and solve it using non-linear finite element procedures. We use the procedures (non-linear explicit dynamics with Total Lagrangian formulation) that do not require iterations even when applied to non-linear problems and are, therefore, amenable to computing the intra-operative brain deformations in real time (under 150 s) on a standard PC. =

| | + | <h3>Objective</h3> |
| | + | The goal of this project is to port existing robot control software for Robopsy and integrate it into 3D slicer using OpenIGTLink. |

| − | If a blank space is the first character for a Wiki line, the following text will be listed in a dashed box, such as the one appearing at the top of each Site and Project Page containing the links to go back to previous pages. Note, that if you entered the edit mode via any of the subheading edit links, upon a "Save page" the blank space at the top of the Wiki page will be removed. Therefore, you will need to manually add the blank space to maintain the dashed text box at the top of the page. Dashed boxes are also used at the bottom of the Project Pages to link to applicable Project Week pages.

| + | <h3>Approach, Plan</h3> |
| | | | |
| − | "In Press" publications will be listed in two places on the Wiki (in the "In Press" sections on the Publications page and on the appropriate Project page(s)). "In Press" publications will not be added to the Publications DB.
| + | The method performs robot/image registration using fiducial markers and robot control. The following modifications will be performed: |
| | | | |
| − | "In Print" publications will be added to the Publications DB with the appropriate Grant number (linking it to the search on the Publications DB) and with the appropriate Project page URL added as a keyword (linking it into the Project page). Once the publication is added to the DB, it will be removed from it's listing in the two "In Press" sections mentioned above.
| + | * The controller code will be modified and connected to the OpenIGTLink. |
| | | | |
| − | Write access for the publications database will be given out to a few select individuals. If you do not currently have write access to the publications database, please send the following information to John Melonakos at (jmelonak at ece.gatech.edu), for "In Print" publications only: 1) the final printed version of the PDF, 2) the bibtex entry for the publication, 3) the NA-MIC Project URLs against which this publication should be linked, and 4) any other files that you would like to add to the publication database for this publication.
| + | * The module will be modified to add widgets for performing the registration and robot control tasks. |

| + | * Have used Skeleton Generator to generate template code for 3D Slicer module to collect fiducials. The registration algorithm was modified. The location of each fiducial marker on the robot was determined. The registration algorithm employs the position of markers on the robot and the fiducial positions which are collected from the image. The initial position for the needle holder was determined for the registration. The possibilities of adding GUI widgets to the registration module in the 3D slicer were discussed with collaborators. |
