February 15, 2007: Registration

A list of priorities concerning meshing, visualization, and computational capabilities for the May 2007 Conference in Beijing was discussed. [pdf] The goal for the conference is to present an end-to-end solution: preoperative data acquisition, mesh generation, optimal laser control, intraoperative data acquisition, mesh registration, calibration, visualization, and feedback.

I. Mesh registration is the highest priority. The current plan is to attack mesh registration in two steps.

1.

Use FFT to eliminate rigid body motions between two sets of 3d images. Current progress on this will be presented at the meeting on February 22, 2007. 2.

Once rigid body motion has been eliminated, relatively small deformations of the mesh can be used for registration of intraoperative images.

Also needed is to agree upon a mesh file format in which meshes generated by LBIE can be viewed seamlessly in Volrover.

II. The Volrover server must be updated so that it is intranet aware with the computational server on Lonestar. i.e. David and Bongjune must communicate to discuss how to connect Hp3d with Volrover via XML-RPC. Also, the machine to run the Volrover visualization server must be decided upon.

III. Hp3d must be made internet aware of the data server in Houston to transfer the MRTI thermal images. Choosing a suitable objective function for the calibration problem is still work in progress.
