Problems solved by technology

[0002] Existing large-scale medical magnetic resonance imaging equipment is expensive, oppressive to patients, unable to examine and diagnose sitting or standing people, and more critically, traditional designs require magnet devices to be placed on a fixed earthquake-proof foundation above, and need to build an independent shielding room
Therefore, it is impossible to move to the site, and there is nothing to do when an on-site inspection or a quick inspection is required

Embodiment 1

[0018] Embodiment 1: A movable low-field nuclear magnetic resonance imaging system, including a spectrometer, a magnet, a computer, a radio frequency power amplifier, a gradient power amplifier and a coil, and a mobile magnet frame 1, such as Figure 1 to Figure 4 As shown, the magnet is a rotatable low-field magnet 2 mounted on a mobile magnet frame 1, the spectrometer is a mobile spectrometer, and the low-field magnet 2 is a U with a field strength of less than or equal to 0.2T. Type permanent magnet, the low-field magnet 2 has a shield 3 symmetrically embedded in the magnet walls on both sides. The mobile spectrometer is driven by the mobile magnet frame 1 to move, and is powered by a battery or directly connected to AC power.

[0019] The mobile magnet frame 1 is equipped with four wheels 4 at the bottom and a mounting table 5 at the top. The mounting table 5 rotates 360° around its center position in a plane parallel to the upper surface of the mobile magnet frame 1, so The...

Abstract

The invention discloses a movable low-field nuclear magnetic resonance imaging system which comprises a movable spectrometer, a magnet, a computer, a radio frequency amplifier, a gradient power amplifier and a coil, as well as a movable magnet frame, wherein the magnet is a rotatable low-field magnet arranged on the movable magnet frame, and a shield is embedded in the low-field magnet. The movable low-field nuclear magnetic resonance imaging system combines the low-field magnet with the movable magnet frame, has small equipment volume and light weight and can carry out fast and timely medical examination in emergencies, rescue scenes, playgrounds, countrysides and other special occasions without being limited by time and place; the low-field magnet can realize omni-directional rotation on the magnet frame, adjust the height of a magnetic field according to needs, carry out accurate examination and diagnosis on a patient in any posture and body position and further reduce the motion of the patient; the adoption of the low magnetic permanent magnet has low maintenance cost and low cost and reduce the production cost; and the movable low-field nuclear magnetic resonance imaging system has good openness, can not cause the oppression to the patient, is applicable to local examination or interventional therapy of the head, the limbs and the like, and is particularly applicable to thorough examination of infants.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to a movable low-field nuclear magnetic resonance imaging system. Background technique [0002] Existing large-scale medical magnetic resonance imaging equipment is expensive, has a sense of pressure on patients, and cannot check and diagnose sitting or standing people. More importantly, traditional designs require that the magnet device be placed on a fixed earthquake-proof foundation And need to build a separate shielded room. Therefore, it is impossible to move to the site, and cannot do anything about the situation that requires on-site inspection and quick inspection. Summary of the invention [0003] The purpose of the present invention is to provide a mobile low-field nuclear magnetic resonance imaging system, which has simple structure, convenient operation and strong practicability. It is a fast, fast, and practical system that can be used in emergency departments, rescue sites,...
