Functional Magnetic Resonance Imaging (fMRI) is fast becoming the diagnostic tool of choice for mapping neuro function in the brain. Non-invasive, no ingestion or infusion of tagged material required, and radiation free, fMRI maps neurological function through blood oxygen level dependent (BOLD) MRI scans of the brain. This technique measures heightened oxygen levels within a region of interest in response to external stimuli.

Analyzing maps generated by this technique yields valuable information that can help guide surgical intervention procedures. Consequently, technology that helps develop accurate and specific exam reports is essential.

GE Healthcare Brainwave

BrainWave imaging software is an easy-to-use analysis and visualization tool for functional brain image data acquired with BrainWave RT. BrainWave enables processing, analysis, 3D rendering and display of results from BOLD MRI scans.


  • Provides retrospective motion correction for patient motion.
  • Activation maps generated using Generalized Lineal Model (GLM) analysis.
  • Sophisticated visualization techniques fuse analysis results with anatomical data.
  • Clear visualization with color activation maps and interactive thresholding.
  • Paradigms saved in the DICOM private structure for fast analysis.
  • Full integration with AW filming, networking, and archiving.
  • Full DICOM fidelity.
  • Ability to transfer activations into high resolution 3D DICOM data sets for neurological applications.


GE Healthcare BrainwaveFeatures

  • BrainWave PA lets you interactively view and edit fMRI data. It can reside on the scanner or on your AW station.
  • Software reads volumetric T1-weighted acquisitions in addition to fMRI acquisitions.
  • Processing steps for fMRI data include:
    • Six parameter rigid body motion correction via registration to the first volume.
    • Spatial filtering.
    • Segmentation of the anatomical data so that outer layers of non-brain signal are removed.
    • GE Healthcare BrainwaveRegistration of fMRI data sets to the structural data set.
    • Calculation of statistical maps corresponding to task-based activation.
    • Formation of Burnt In Pixel (BIP) maps outlining the area of activation in white on the structural scan.
    • Calculation of DTI fiber tracks (option with BrainWave Fusion).
  • View functional data overlaid on the structural image in 2D or 3D renderings. Add annotations or change color and opacities.
  • BrainWave Fusion (option) lets you display white matter tracks with functional data on a high-resolution anatomical image.

System Requirements

  • AW VolumeShare 5 or above
  • One or two display monitors
  • BrainWave PA requires BrainWave RT
  • BrainWave Fusion requires BrainWave PA and DTI FiberTrak

  • Intended Use

    The GE Functional Brain Mapping Option is a software and hardware package that can be used to acquire, process, and display the results of BOLD MRI scan studies taken in the presence of synchronized stimuli presented to a person being scanned. When interpreted by a trained physician, these results may be useful in the determination of a course of treatment.
