Abstract

Field measuring equipment of a magnetic resonance imaging device comprises a supporting rail (10), a plurality of detection rods (20), a plurality of Hall probes (30), a sliding piece (40) and a plurality of adjusting rods (50). One end of each detection rod is rotatably connected with the supporting rail, and the rotation axis is perpendicular to the length direction (L) of the supporting rail. The rotating axes of the plurality of detection rods are intersected at a central point (Q). The Hall probes are arranged on the detection rods in a one-to-one correspondence mode. The distances between the Hall probes and the central point are equal. The sliding piece is slidably connected with the supporting rail in the length direction of the supporting rail. One ends of the adjusting rods are rotatably connected with the detection rods in a one-to-one correspondence mode, and the other ends of the adjusting rods are rotatably connected with the sliding pieces. The field measuring equipment is small in structure, parts of the magnetic resonance imaging device do not need to be disassembled during use, and detection efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to a measuring field device of a magnetic resonance imaging device, in particular to a measuring field device of a magnetic resonance imaging device with a compact structure and easy to use. Background technique [0002] As the current mainstream medical imaging equipment, magnetic resonance imaging device plays an important role in clinical diagnosis and patient examination, and its imaging quality directly depends on the uniformity of the spherical imaging area in the center of the main magnetic field. Therefore, it is necessary to measure the magnetic field in the central spherical imaging area of ​​the magnetic resonance imaging device with a measuring field device to determine whether the uniformity of the magnetic field meets the requirements. At present, the commonly used measuring field equipment is bulky, and some parts of the magnetic resonance imaging device need to be disassembled during the measurement, resulting in c...
