Embodiment Construction

[0035]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] Traditional magnetoencephalography uses a superconducting quantum interferometer as a magnetic field detector. The detector needs to be kept at an extremely low temperature to work properly, so it needs to be packaged and fixed in a Dewar tank filled with liquid nitrogen, and communicated with the outside world. The vacuum insulation layer with a thickness of several centimeters limits the detector’s close contact with the scalp to obtain st...

Abstract

The invention provides a magnetoencephalography system and a method of operating the magnetoencephalography system, and relates to the technical field of medical imaging. The magnetoencephalography system comprises a flexible brain magnetic cap having inserting grooves, and a limiting clamping sleeve which cooperates with the inserting grooves and comprises a fixing part, the fixing part is arranged on the surface, adjacent to the inserting grooves, of the limiting clamping sleeve, and the limiting clamping sleeve is used for fixing an atom magnetometer into the inserting grooves. According to the magnetoencephalography system provided by the invention, by virtue of the flexible brain magnetic cap with the inserting grooves, the limiting clamping sleeve cooperating with the inserting grooves and linkage matching between the limiting clamping sleeve and the fixing part on the adjacent surfaces of the inserting grooves, the purpose of portable detection of brain magnetic signals of a subject is achieved. The flexible brain magnetic cap provided by the invention can adapt to head contours of different sizes within a certain range, the portability of magnetoencephalography detection is improved, and the wearing experience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to a magnetoencephalogram system and an operation method of the magnetoencephalogram system. Background technique [0002] Magnetoencephalography is a functional brain imaging technology that detects weak magnetic fields generated by electrical nerve signals. Functional area positioning, brain cognitive neuroscience research, etc. [0003] However, current magnetoencephalography systems based on superconducting devices require detectors to be placed in dewar tanks filled with liquid helium, resulting in bulky and bulky systems that are expensive and expensive to maintain. Atomic magnetometers based on the optical pumping effect can also be used to detect magnetoencephalographic signals. At present, the portable magnetoencephalogram detection devices researched at home and abroad have many shortcomings, such as having to be fixed on the scanning bed, and the wearing experien...
