Embodiment Construction

[0035] In order to make the above objects, features and advantages of the present invention more obvious and comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] In the following description, many specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways than those described here, so the present invention is not limited by the specific embodiments disclosed below.

[0037] As described in the background technology, the detection of the electrical center of the magnet in the prior art is carried out by measuring the field distribution of the spherical area, calculating and judging some characteristic quantities, and the measurement panel must be rotated during the test, resulting in a test Long time, complex manual operation, and low accuracy of measurement results. Therefo...

Abstract

The invention discloses a detection device and method for a magnetic-body electrical center. The detection device comprises a probe array, a main measuring shaft, a radio frequency transceiver and a control processor, wherein the probe array comprises a preset number of measuring probes which are arranged in a linear manner; the probe array is arranged on the main measuring shaft; measuring scales relative to the position of a central reference point are formed at one end of the main measuring shaft; the central reference point is any point on the main measuring shaft, where the probe array is located; the radio frequency transceiver is used for transmitting a radio frequency pulse signal and receiving an analog voltage signal; the control processor comprises a control unit and a data processing unit. By adopting the technical scheme of the invention, the time for measuring the magnetic body electrical center is shortened, the operation complexity caused by too much manual operation is reduced, and the precision of the measurement result is improved.

Description

technical field [0001] The invention relates to the technical field of magnetic resonance, in particular to a detection device and method for a magnet electrical center. Background technique [0002] Magnetic Resonance Imaging (MRI, Magnetic Resonance Imaging) is an important field of nuclear magnetic resonance applications. Due to its excellent resolution of human soft tissues, imaging parameters can provide rich diagnostic information, and no ionizing radiation damage to the human body. Resonance system has become one of the main tools of medical clinical diagnosis. The magnet is an important part of the magnetic resonance system. When the magnet is designed, the magnetic field generated by the magnet changes along the direction of the main axis of the magnet in a symmetrical distribution. In general, a point within 10mm away from the center of symmetry or the center of symmetry in the direction of the main axis The point is called the ideal electrical center of the magne...
