Problems solved by technology
[0006] At present, the research on functional MRI changes caused by acupuncture and moxibustion mainly focuses on the acupoints of the extremities, but there is a lack of research on the changes before and after stimulation of acupoints on the head
At the same time, the cranial coils currently used in MRI surround the subject's head and neck. The arrangement of the coil units in the cranial coils does not take into account the needs of acupuncture and moxibustion. It is impossible to study the immediate effect of scalp acupuncture treatment, and acupuncture physical therapy is not supported. Simultaneously with clinical scans for MRI

Embodiment Construction
[0036]The present invention is further described below with reference to the accompanying drawings and examples.
[0037]Such asFigure 1-17As shown, a head coil assembly 100 for magnetic resonance imaging includes a plurality of coil units and a housing for supporting the coil unit, the housing including a left housing 1, an intermediate housing 2 and right housing 3, the left housing, the intermediate housing 2, and the right housing 3 are three separate components, separately. The left housing 1, the intermediate housing 2, and the right side housing 3 are combined together to form a housing chamber 10 having a lower opening 12, and the left housing 1, an intermediate housing 2 And the right housing 3 provides one or several openings 11, 21, 31, respectively, and the opening 11, 21, 31 communicate with the receiving chamber 10. The left housing 1, the right housing 3 is symmetrically disposed on the left and right sides of the intermediate housing 2.
[0038]Further, the left side housi...

The invention discloses a head coil component for magnetic resonance imaging. The head coil component comprises a plurality of coil units and a shell for supporting the coil units, wherein the coil units are arranged into a left coil unit group, a middle coil unit group and a right coil unit group, and the coil units in the left coil unit group and the right coil unit group are symmetrically distributed. The head coil component can satisfy the clinical scanning, magnetic resonance imaging scanning and acupuncture physiotherapy requirements of the magnetic resonance imaging.
Description
[Technical field][0001]The present invention relates to a magnetic resonance imaging technique, and more particularly to a radio frequency coil for magnetic resonance imaging.【Background technique】[0002]Magnetic resonance, also known as magnetic resonance imaging, MRI, spinimaging, Nuclear Magnetic Resonance Imaging, NMRI, is another major progress in medical imaging after CT. Since the application of the 80s, it has developed with a very fast speed. The basic principle is to place the human body in a special magnetic field. When the subject is placed in a magnetic field, the hydrogen atoms in the body can be polarized. The hydrogen radio range is used in the human hydrogen radio range, causing hydrogen atom core resonance, and absorb energy. After the radio frequency pulse is stopped, the hydrogen atom nuclear is emitted by a specific frequency, and the absorbed energy is released, and the receiver is included in the body, and an image is obtained after the electronic computer is p...
