BrainWave

Fast, easy fMRI analysis.

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.

Highlights

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.

Key Features

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.
- Registration 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.

GE Healthcare Brainwave

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.
