Problems solved by technology

[0003] However, since the MRI system generally works in a complex environment with multiple noise sources, if you want to get rid of the limitations of the shielding system and realize the lightweight, miniaturization and even mobility of the MRI system, it is convenient to deploy the MRI system in any part of the hospital. Unshielded but needed departments, ambulances, and bedside monitoring need to solve the problem of noise reduction of electromagnetic interference noise

Abstract

A noise pickup device for detecting electromagnetic noise of a magnetic resonance system is provided with a shell, a human body detected part containing space is formed in the shell, and a noise pickup coil is arranged in the middle in the shell and used for picking up space electromagnetic interference and noise coupled to a human body through induction. A human body surface noise pickup device and a detection object clamping mechanism are arranged on the two sides of the noise pickup coil in the shell respectively, a circuit board is arranged on the outer side of the shell, and an impedance matching circuit is arranged on the circuit board. The device can be tightly attached to an imaging object during detection, noise or interference introduced by the imaging object can be accurately obtained, and the device is easy to fix and operate.

Description

【Technical field】 [0001] The invention relates to the technical field of magnetic resonance for medical diagnosis, in particular to a noise pickup device for detecting noise in magnetic resonance imaging. 【Background technique】 [0002] As a multi-parameter, multi-contrast imaging technology, magnetic resonance is one of the main imaging methods in modern medical imaging. Its advantages such as no radiation, high contrast resolution, etc. have been significantly superior to imaging equipment such as CT and X-ray machines. , has received much attention in clinical applications, and has become a vital part of the high-end medical equipment field. In the future medical equipment field, magnetic resonance will have greater development and market. [0003] However, since the MRI system generally works in a complex environment with multiple noise sources, if you want to get rid of the limitations of the shielding system and realize the lightweight, miniaturization and even mobilit...
