Abstract
A biomagnetic field map display apparatus for measuring a biomagnetic field generated by a biotest sample at positions arranged in rows and columns and displaying a magnetic field map obtained by processing the measured biomagnetic field. An analysis data display area waveform-displays the measured biomagnetic field at channels in a row or a column of channels which are arranged in rows and columns so as to respectively correspond to the positions. A particular channel is designated as a reference channel for an averaging process out of the plurality of channels or different channels therefrom at which different biosignals from those of the biomagnetic field are acquired from the biotest sample. Means for averaging-processing the measured biomagnetic field using the designated particular channel as the reference channel displays in the analysis data display area a map on the averaging-processed biomagnetic field.
