CPC A61B 5/242 (2021.01) [A61B 5/743 (2013.01); A61N 1/0456 (2013.01); G09G 5/37 (2013.01); G09G 2380/08 (2013.01)] | 6 Claims |
1. A biomagnetic field measurement processing apparatus comprising:
circuitry;
and a memory storing computer-executable instructions that cause the circuitry to execute:
reconfiguring a current signal from a biomagnetic field signal measured from a subject;
calculating a path of a nerve axon or a muscle fiber in a morphological image of the subject, wherein the morphological image is displayed on a display device
generating plurality of first virtual electrodes positioned along the path and a plurality of second virtual electrodes on respective sides of the path with respect to each of the plurality of first virtual electrodes;
extracting current waveforms of a plurality of inward currents that are current components directed toward the nerve axon or the muscle fiber from around the nerve axon or around the muscle fiber from the current signal, wherein the current waveforms are extracted at the plurality of second virtual electrodes and comprises at least a first current waveform and a second current waveform;
generating a summed current waveform to be displayed on the display device by adding to each other the first current waveform extracted at one second virtual electrode of the plurality of second virtual electrodes on one side of the path and the second current waveform extracted at a corresponding second virtual electrode on an opposite side of the path than the one second virtual electrode at which the first current waveform was extracted;
and displaying the summed current waveform together with to the first current waveform and the second current waveform in a user interface on the display device in order to evaluate neural function or muscle function.
