Project Description

Objective

This project will investigate approaches to ultrasound-based visualization and navigation in the context of neurosurgery. The goal will be to develop a persistent representation of intra-operatively acquired 2D US data that can be visualized in conjunction with pre-operative MR data.

Approach, Plan

  • We will brainstorm approaches based on current Slicer and PLUS software capabilities. Possible approaches include
    • real-time 3D ultrasound reconstruction
    • painting US data onto predefined visualization planes.

Progress

  • We developed a python module that can be used to reconstruct ultrasound volumes online from Slicer, via an active PLUS Server connection.
  • The ultrasound volume can be generated rapidly, visualized and navigated via Slicer, e.g. using a stylus and the VolumeResliceDriver module.
  • We tested the module on data an existing AMIGO neurosurgery case, and investigated navigation via a Leap Motion gesture controller.
