The azimuth projection for the display of 3-D EEG data.
Electroencephalogram (EEG) is a scalp record of the neural electric activities of the brain. There are many kinds of methods to display the EEG data, such as a projective plane or the realistic head surface. In this work, one of the atlas projection methods, azimuth conformal projection, was tested and recommended as a new way of a planar EEG display. The method details are given and numerically compared with the normal projective plane display. The results indicate that the azimuth projection has many advantages: the transform is simple, convenient, and it can keep all the information. It shows all the information in the 3-D data within a projective plane without distinct shape change. Therefore, it can help to analyze the data effectively.
