Brain tumor detection device based on magnetic resonance electrical impedance tomography

Abstract

The invention discloses a brain tumor detection device based on magnetic resonance electrical impedance tomography. The brain tumor detection device comprises a main body, a base and a strip-shaped plate, a through hole is formed in one side of the main body, the base is horizontally and fixedly connected to the bottom of the main body, the strip-shaped plate is located on one side of the base, and a horizontal moving mechanism used for horizontally moving the strip-shaped plate is arranged in the base; a strip-shaped groove is horizontally formed in the inner wall of the through hole, a brush plate matched with the strip-shaped groove is slidably arranged in the strip-shaped groove, a first rotating mechanism used for rotating the brush plate is arranged in the main body, a hollow box is horizontally arranged over the strip-shaped plate, and a rectangular groove is formed in the bottom of the hollow box; and lifting mechanisms used for lifting the hollow box are arranged at the two ends of the top of the strip-shaped plate correspondingly, a moving box is horizontally arranged over the hollow box, and a moving plate is horizontally and slidably connected to the top of the moving box. According to the invention, the situation that the detection effect is poor when the patient rotates the body by himself or herself is avoided, so that the detection accuracy is improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a brain tumor detection device based on magnetic resonance electrical impedance imaging. Background technique [0002] Magnetic resonance electrical impedancetomography (MREIT) is a new type of impedance imaging method that combines bioelectrical impedance imaging with magnetic resonance imaging. In this method, the imaging target is placed in the magnetic resonance equipment, the electrical impedance imaging equipment is used to obtain the surface electric field characteristics of the target object, and the magnetic resonance equipment is used to measure the magnetic field characteristics inside the target object, and finally the electrical impedance image is reconstructed according to the imaging principle formula. This method can weaken the disadvantages of traditional methods, obtain high-precision, high-resolution images of biological tissue impedance distribution, provide ...

Problems solved by technology

[0003] The existing brain tumor detection device based on magnetic resonance electrical impedance imaging does not have the function of cleaning and disinfecting the detection device, which may cause the generation of germs during use and reduce the use effect of the detection device. , the patient needs to turn the body by himself, and when the patient turns by himself, the rotation may not be standard, which reduces the detection effect
