Magnetic resonance examination bed leveling device

Abstract

The invention discloses a magnetic resonance examination bed leveling device, which comprises a support and a leveling detection mechanism arranged on the support and located above a magnetic resonance examination bed, and the magnetic resonance examination bed comprises a bed platform, a bed frame for supporting the bed platform and a plurality of adjustable trundles arranged at the bottom of thebed frame and used for adjusting the bed platform to be horizontal; the device is characterized in that the leveling detection mechanism comprises a suspension mechanism arranged on the support and adistance measurement sensing device arranged on the suspension mechanism; the suspension mechanism comprises a hanging rope of which the top is connected with the support through a rotating shaft anda plumb bob fixed at the bottom of the hanging rope; wherein the distance measurment sensing device comprises more than three distance measuring unit mechanisms which are arranged on the plumb bob and keep horizontal balance, each distance measuring unit comprises a horizontal rod fixed with the plumb bob and a distance measuring sensor which is arranged on the horizontal rod and points to the bed platform, and at least three distance measuring sensors are triangularly distributed in the horizontal plane. The device is simple in structure, convenient to operate, high in efficiency and low inmanufacturing cost.

Description

technical field [0001] The invention relates to a magnetic resonance examination bed leveling device. Background technique [0002] Magnetic resonance is an atomic nucleus with a non-zero magnetic moment. Under the action of an external magnetic field, the spin energy level undergoes Zeeman splitting, and the physical process of resonantly absorbing radio frequency radiation of a certain frequency; during magnetic resonance examination, the patient needs to be pushed into the Inside the magnet, after a series of scans, the patient is pushed out from the inside of the magnet to complete a magnetic resonance scanning process; through the above, it can be seen that in the series of scanning processes of the patient, the accuracy and stability of the examination table operation play a key role in the entire scanning process The flat performance of the bed improves the quality of inspection images and the comfort of patients. [0003] However, in the actual installation process,...

Problems solved by technology

[0003] However, in the actual installation process, there are many uncertain factors that lead to the flatness of the bed, such as the unevenness of the ground in the shielding room, the accumulative tolerance of the bed processing, and the installation accuracy. Or the liner tool is used to level the bed, but this tool lacks accuracy and takes a long time to adjust, and due to the limitation of the large size of the examination bed, the leveling operation cannot be performed conveniently; so it is necessary to invent an accurate and convenient The leveling device of the magnetic resonance examination table to solve the above problems
