2015 Winter Project Week: Neurosurgery Case Review

• 

  Projects List

• 

  Example of Pre-Op MR and Intra-Op Ultrasound

Key Investigators

• Steve Pieper, Isomics
• Jim Miller, GE
• Alireza Mehrtash, Sandy Wells, Tina Kapur, Ron Kikinis, BWH

Project Description

Objective

• Review data from recent AMIGO neurosurgery case (MR, US)
  • Identify and evaluate sources of error
  • Review options for improving overall imaging accuracy

Approach, Plan

• Alireza to collect all MR and US data for this case
• Manual and automated registration tools to be used for review
• Brainstorming about how to either fix the current system or circumvent Brainlab so that all pieces of the system can be debugged

Progress

• Held a breakout session to evaluate data from several cases
  • Reviewed extent and possible causes of mis-registrations
  • Evaluated possible solutions
• Alireza to make anonymized datasets available in public repository with descriptions of the various datasets
• Steve to work on benchtop system to emulate neurosurgical setup (with Jim and with help from Andras and Tamas)
• Matt and Sandy to take example data and attempt feature-based US to US registration
• Sandy and Steve to explore mechanics-based interpolation
