The present invention relates to an open-typed magnetic induction imaging measuring device, consisting of a controller, an actuating single passage, an offset signal passage, a power magnifying circuit, a relay array, a winding sensor array, an array of difference amplifying circuits, a switch array, a signal regulating circuit, a signal amplifying and signal regulating circuit, a signal scale adjusting circuit, an A/D transferring circuit, a circuit for limiting drift of switch temperature and an external communication port. Imaging of the present invention is relatively simpler than global imaging, while requirement about hardware system in imaging of the present invention is lower than that of the global imaging, which means lower parameters about passage values which activate the signals. The present invention can satisfy needs of clinical medicine toward small sized, cheap, noninvasive and quick test instrument and imaging equipment with function of real time monitor.
