Objective

Real-time ultrasound data is used to track the shifting of intracranial anatomy during neurosurgery. This is accomplished with a stationary ultrasound probe that is mounted away from the surgical site, and operates transcranially so as to be completely unobtrusive to surgical activities. Coordinating the use of this device with Slicer and BrainLab:

• Registering the data obtained from it with pre-op images (MRI, CT, etc.) (Fig. 1)
• Using this data to modify/deform the pre-op images in order to maintain a more accurate representation of intraoperative anatomy.
