High sensitivity open type magnetic induction image measuring device

Abstract

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.

Description

technical field [0001] The invention relates to medical imaging diagnostic equipment, in particular to a high-sensitivity open magnetic induction imaging measuring device. Background technique [0002] Since the discovery of X-rays, the development of medical science and clinical medicine has produced a qualitative leap. Especially in the past 20 years, the combination of traditional radiation technology, electromagnetic technology and computer has produced a series of medical imaging diagnostic equipment including CT, magnetic resonance imaging, etc., which has changed the concept and method of medical diagnosis and treatment, and developed on this basis. The emerging medical imaging diagnosis and treatment system has become the three major diagnosis and treatment systems of contemporary medicine alongside the internal medicine diagnosis and treatment system and the surgical diagnosis and treatment system. Although medical imaging diagnostic technology has made great progr...

AI Technical Summary

Problems solved by technology

[0005] (1) The error caused by the contact impedance of the electrode skin seriously affects the measurement accuracy

[0006] (2) Poor current directivity causes low image resolution

[0007] (3) When applied to head imaging, the high resistivity of the skull causes a large attenuation of the injected current, which seriously affects the imaging effect

The imaging effect is not ideal, etc.

And because the object to be measured is located in the middle of the coil, it is not conducive to clinical use
