Neuro Option

This option offers specialized modules to analyze medical images obtained from CT or MR imaging. Diffusion weighted MR imaging (DWI) is used to image the rate of water diffusion in tissues like brain or muscle. This option allows the user to compute the apparent diffusion coefficient (ADC), fractional anisotropy (FA), and directionally encoded color (DEC) maps. Diffusion tensor imaging (DTI) aims at localizing and visualizing fiber tracts in the human or primate brain and is supported by several modules. Brain perfusion analysis is supported based on tracking a contrast bolus in a time series of MR or CT images.

Features


Medical image analysis for DTI and Brain Perfusion

After loading your CT or MRI data, mesh the volume with an optimized 3D
grid, assign material properties and boundary conditions. Export the result
to an external FEM application to perform simulations and import the output
back into Amira to visualize it.
