Abstract
Cerebral nerve activity estimated by means of magnetoencephalography (MEG) is usually evaluated by fusion with anatomical images such as MRI, X-ray CT. Therefore, in order to diagnose using MEG measurement results, it is very important to consider not only accuracy of MEG source estimation but also total accuracy including fusion with these anatomical images. In this report, we introduce a phantom which is capable of detecting the source location from these anatomical images as well as MEG measurement, and show this phantom can be used for the evaluation of MEG source estimation including fusion with anatomical images.
