2. Problem
Novel MRI Compatible Head Frame
Neurosurgeons have struggled with exact localization and treatment of brain pathology even in the modern era
MR guided stereotactic procedures currently allow for single trajectories for placement of brain stimulators, electrodes, ablations or biopsies
Multiple trajectories would entail significant additional time and morbidity for the patient- the procedure would no longer be minimally invasive
Can we develop a new way to achieve multiple exact (as many as 18, mean=12) trajectories to manage old and emerging treatments in pediatric and adult neurosurgery?

3. Novel MRI Compatible Head Frame
Current Practice: We cannot easily make more than 1 trajectory in an MRI environment for neurosurgical treatment

The Job
Job: Creation of an instrument that will allow for minimally invasive multiple exact trajectories, unilaterally or bilaterally, in an MRI environment. Incorporation of augmented reality into this environment would create a further safety net for surgical planning.

4. Additional needs
Novel MRI Compatible Head Frame
Augmented Reality platform: visualization of minimally invasive brain anatomy
Tool and implant(s) projected and displayed in 3D intracranial space
May be a gateway to further significant advances in neurosurgery-MRI environment

5. Advantages: Other Environments
Novel MRI Compatible Head Frame
Frame can be used in combination with stereotactic technology in the traditional operating room with additional AR capability for minimally invasive navigation.
Stereotactic technology and tool recognition with appropriate AR technology for augmented navigation would increase efficiency and safety in this environment as well

6. Constraints All development must be MRI compatible
Novel MRI Compatible Head Frame
All development must be MRI compatible
Accurate stereotactic fusion of images and navigation
Multiple technologies must be incorporated and working in unison
Streamlining graphical AR interface

7. Summary
Novel MRI Compatible Head Frame
The field of neurosurgery continuously strives to become less invasive while providing better outcomes safely.
The development of this technology would provide:
1. A new environment to further advance the field in Pediatric and Adult NS
2. A novel head frame to open the door to further procedures in an MR-OR
3. Combine real-time Clinical Care and Augmented Reality for the first time
The clamp pictured is the Mayfield Clamp developed by Frank Mayfield MD ( ) in 1973.
This clamp is used thousands of times in the operating room every day in every corner of the world and it revolutionized neurosurgery since its invention
Our new type of head frame may open another venue in the world of clinical neurosurgery- the Stereotactic Augmented Reality MR based operating suite.
