Be imaged (spin imaging), Magnetic resonance imaging (Nuclear Magnetic Resonance Imaging,
NMRI), it is the another major progress of the Medical Imaging after CT.Since the eighties is applied, it is with pole
Fast speed is developed.Its general principle is placed in human body in special magnetic field, when measurand is placed in
After in magnetic field, its internal hydrogen atom can be polarized.With hydrogen nuclei in radio frequency pulse excitation human body,
Cause hydrogen nuclei to resonate, and absorb energy.After radio-frequency pulse is stopped, hydrogen nuclei is sent out by specific frequency
Go out electric signal, and the energy of absorption is discharged, included by external receiver, through electronic computer
Image is obtained after processing.
The information content that MRI is provided not only is more than other many Imagings in Medical Imaging, and is different from
Existing Imaging, therefore, its diagnosis to disease have very big potential superiority.Because it can be straight
Connect the body tomographic image for making cross section, sagittal plane, coronal-plane and various inclined-planes；And without ionising radiation, to machine
Body does not have harmful effect, thus is used more and more in medical domain.
Radio-frequency coil is the important component of magnetic resonance imaging system, for producing radio-frequency pulse, excite by
Sweep object, produce magnetic resonance signal；Then, radio-frequency coil receives magnetic resonance signal, passes through follow-up number
According to processing, 2D the or 3D pictures of scanned object are obtained.It is total to preferably gather the magnetic at scanned position
Shake signal, improves the signal to noise ratio of image, and local coil is widely used.Local coil is often directed to
A certain specifically scanned position and design, such as local coil for ankle, the local coil of wrist,
The local coil of backbone, local coil for head etc..
The existing local coil for head, that is, head coil, including outermost hard plastic shell,
Plastic shell need to do enough receiving spaces, and build is smaller to meet the scope on probation of 95% crowd
Head part, possibly remote from coil receiving unit, cause signal to noise ratio to decline；And existing head coil is duricrust
Profile, do not support to do the clinical scanning of acupuncture therapy and magnetic resonance imaging while carry out.
【The content of the invention】
The technical problems to be solved by the invention are to provide a kind of head coil component for magnetic resonance imaging,

Form accommodating chamber afterwards together, the accommodating chamber has a under shed, and the left shell, middle casing and
Right shell sets one or several perforates respectively, and the perforate is connected with accommodating chamber.
Preferably, the housing parts of the lower opening can be raised outwards.
Preferably, the left shell, right shell and middle casing are fixed by screw.
Preferably, the edge of the left shell, the edge of right shell and middle casing is stacked, and described
Left shell, the edge of right shell are located at the inner side at the edge of middle casing.
Preferably, the top of the middle casing, rear portion, front portion are equipped with perforate.
Preferably, the left shell, middle casing and right side are made up of flexible material.
Preferably, the edge of the left shell, middle casing and right shell is stacked the big I of surface area
With change, to obtain different size of accommodating chamber.
Preferably, the forward and backward opposite segments of the middle casing are fettered by bandage.
Preferably, the left shell is identical with size, the shape of right shell, and relative middle casing pair
Claim arrangement.
Preferably, the left shell, the front lower portion of right shell are provided with breach.
Present invention contrast prior art has following beneficial effect：The head coil modular construction of the present invention is relative
Simply, it is easily manufactured；Whole coil block is made of flexible material, and accommodating chamber size is adjustable, with head compared with
Press close to, the magnetic resonance signal compared with high s/n ratio can be obtained；In addition head coil component is provided with several larger open
Hole, the needs of MRI scan and acupuncture therapy can be met.
