Use BESA Research for reviewing patient data. To make decisions easier, BESA Research supports the evaluation of interictal activity with 3D Mapping, source montages and filters optimized for evaluation of epilepsy data.
Spike Hunting: Find the first spike, let the automated search engine do the rest!
Just mark the first spike manually and then run the fully adjustable pattern search to find similar events quickly and reliably. Optionally, refine the search pattern using the auto-averaged spikes.
Average spikes for discrete or distributed source analysis. Analyze spike onset and check for propagation. Finally perform a source analysis using the averaged data to analyze e.g. the
Use BESA MRI for the segmentation of MR data and for a co-registration with the EEG. You can calculate an individual head model, and use it in the source analysis of BESA Research to obtain superior localization results.
Source analysis: Get from a spike to its source in 5 mouse clicks!
Interictal spike analysis in MEG
This video demonstrates how to analyse interictal spikes in MEG, using pattern search and dipole source localization.
Ictal activity (spikes)
Use the customizable BESA Research DSA module to search for seizures and to analyze e.g. the onset phase. Use FFT and BESA Research’s FFT 3D phase maps to visualize and understand frequency (band)-specifi c activity and propagation.
Use BESA MRI 3.0 in the same way as for the interictal activity.
