Dartmouth:
This group predicts brain deformations using finite element modelling and then
uses intra-operatively acquired tissue motion data to correct for brain shift.
John
Hopkins Neuroimaging Lab: Example of a system that uses finite element
methods to perform simulations of kinematics (displacements) of the brain
during neurosurgical procedures such tumor growth and intra-operative shift.
University of
Minnesota: The Interventional MR Suite permits performing surgery outside
the MR scanner, pausing to acquire images during surgical procedures by
rolling the patient into the machine (infrequently).
Image Guided Neurologics: Company
that develops tools (eg. Navigus) to allow physicians to access targeted sites
within the brain through a minimally-invasive cranial burr or twist drill hole
rather than the conventional open craniotomy. The Company's technology is
compatible with both real-time Magnetic Resonance Imaging (rtMRI) equipment
which utilizes a "short-bore" magnet and more conventional "long-bore"
scanners. This product is used by the MR group in Minnesota for biopsies.
Sintef
Unimed: Ultrasound IGNS system that acquires 3D ultrasound from a
burr-hole to update the map of the brain several times during the procedure.
