BESA MRI

BESA MRI is a CE-certified software to generate individual head models (FEM) that can be used for EEG and / or MEG source analysis. BESA MRI also allows co-registration of EEG / MEG data with individual MRI data. BESA MRI is the first software that offers an easy, intuitive interface with an integrated workflow guiding the user step-by-step.

MRI data import is easily performed with DICOM, ANALYZE / NIFTI, VMR readers. With a few simple clicks, MRI data is prepared and automatically processed by BESA MRI requiring not much user interaction. This fully automated workflow feature can process all subjects prepared by the user in one cycle, minimizing user interaction time with BESA MRI. Furthermore, BESA MRI’s automated segmentation includes an inhomogeneity correction to correct MRI artifacts, generates a high-quality cortex and scalp reconstruction with optional cortex inflation for enhanced visualization and can even generate an individual head model (BEM, FEM) with 3 layers (scalp, skull, brain – BEM) or 4 layers (scalp, skull, CSF and brain – FEM).

BESA MRI runs in combination with the latest version of BESA Research. Individual head models (BEM, FEM) generated with BESA MRI can be imported by BESA Research for EEG and MEG source analysis. EEG / MEG data can be co-registered with individual MRI data using individually digitized electrode positions or head shape points. BESA MRI includes a unique feature which allows morphing 10-10 standard electrodes (including inferior electrodes) with individual MRI data. Once co-registered electrode coordinates are saved in BESA MRI, they automatically become available in BESA Research. Thus, source images and localizations can be displayed on the individual MRI even if no individual digitization of electrodes has taken place.
