摘要:
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.

摘要:
The present invention, in the physiological magnetic field measuring instrument, recognizes characteristic waveforms (for example, heart beats) repeatedly appearing by physiological activity from measured signal waveforms, registers one of measured heart beats as a reference waveform, evaluates the difference degree of each measured heart beat data from the reference waveform, and executes the averaging process using only waveforms whose difference degrees are less than the allowable value. The present invention registers waveforms whose difference degrees are more than the allowable value as abnormal data and puts them into the display enabled state. Discrimination information is as signed to measurement conditions necessary for measuring the physiological magnetic field and data analysis conditions and when the discrimination information is designated for measurement, the measurement conditions and analysis conditions can be read. By doing this, the physiological magnetic field measuring instrument independently selects good or defective data automatically, and a reliable automatic averaging process can be obtained, and the data processing and operation can be simplified.

A biomagnetic field measuring apparatus has a plurality of fluxmeters disposed externally of a living body and each including a superconducting quantum interference device (SQUID) for detecting a biomagnetic field generated from the living body, the plurality of fluxmeters being operative to detect a temporal change of a component of the biomagnetic field in a first direction which is vertical to the surface of the living body, an operation processor for performing computation for determining a temporal change of a value proportional to a root of square sum of differential value of the first-direction magnetic field component in second and third directions which cross the first direction and computation for integrating the temporal change of the value over a predetermined interval to determine an integral value, and a display for displaying the determined integral value. Distribution of magnetic fields generated from the heart is determined with a small number of fluxmeters.
