Technical field
The present invention relates to magnetic resonance coil technical field more particularly to magnetic resonance Bilateral Symmetry joint while imaging coils.
Background technology
Magnetic resonance imaging (MRI) is started the eighties in last century applied to clinical high-end medical image imaging device.30
For many years, MRI is widely used in clinic, and either equipment installation number still checks person-time all at explosive growth.MRI checks nothing
Radio radiation has many advantages, such as soft tissue resolution height, multi-faceted imaging, multi-sequence im-aging, to disease compared with x-ray plain film, CT
Discovery rate, recall rate significantly improve.But MRI checks that the deficiencies of sweep time is long, contraindication is more restricts its clinical application.
Coil is the important essential component part of one of MRI, to complete magnetic resonance examination and have to coil.Line
The effect of circle is placed in the position for needing to check, MRI scan and signal collection are carried out to receive specific organization.There is spy at certain position
Fixed coils special then has corresponding head, abdomen, joint coils special such as head, abdomen, joint scanning.Existing joint line
Circle once can be only done unilateral joint scanning, take 20 minutes or so.If carrying out Bilateral Symmetry joint scanning (such as bilateral knee
Joint or ankle-joint), it needs after scanning through a lateral joint, places the coil in another lateral joint, carry out repositioning scanning；It is complete
It is taken around 40 minutes at the scanning of two lateral joints.Time-consuming for existing Bilateral Symmetry joint scan method, has office to clinical application
It is sex-limited.Clinically Bilateral Symmetry arthroscopy case is more, there is an urgent need to can be completed at the same time Bilateral Symmetry joint scanning and
Shorten the joint coil of sweep time.
Invention content
The present invention is intended to provide magnetic resonance Bilateral Symmetry joint while imaging coil, can scan Bilateral Symmetry joint simultaneously,
Shorten sweep time, improves scan efficiency.
In order to achieve the above objectives, the technical solution adopted by the present invention is as follows：
Magnetic resonance Bilateral Symmetry joint while imaging coil, including two local coil systems in parallel and control are opened
It closes, control switch includes two switches, and two switches control one of local coil system respectively.
Wherein, local coil system includes coil upper piece and coil bottom sheet, and coil is equipped in coil upper piece and coil bottom sheet.
Further, coil bottom sheet is than coil upper piece softness.
Further, local coil system further includes being set to two partition boards between coil upper piece and coil bottom sheet, two
Partition board parallel interval is arranged, and the lower end of partition board and coil bottom sheet are affixed；
Coil upper piece side is connect with one of partition board, the opposite other side of coil upper piece and another partition board it is affixed or
It is detachably connected.
Wherein, coil bottom sheet and coil upper piece are rectangle.
Further, the length of rectangle is 40cm-50cm, width 25cm-35cm；Divider height is 20cm-30cm.
Further, two local coil systems are arranged side by side, one of local coil system partition board with it is another
One of one local coil system partition board is affixed or integrally manufactured.
Wherein, coil is annular.
The detour shape alternatively, coil takes the shape of the letter U.
Further, coil channel has 4-6.
Compared with prior art, the invention has the advantages that：
The present invention can single-double dual-purpose, be suitable for the case where scanning single side or bilateral scan；Bilateral Symmetry pass is scanned simultaneously
Section, can shorten sweep time, improve scan efficiency；Coil upper piece is flip structure, and the leg of patient is facilitated to put into and take out, and is used
It is convenient.

Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with attached drawing, to the present invention into
Row is further described.
Embodiment one
As shown in Figure 1, the imaging coil simultaneously of magnetic resonance Bilateral Symmetry joint disclosed in the present embodiment, including two in parallel
Local coil system and control switch, control switch include two switches, and two switches control one of local line respectively
Circle system.Control switch is manipulated by scan controller.Control switch in channel can represent left side joint with letter L, R, L, and R is represented
Right side joint.Such as knee joint scan, unilateral knee joint scan can be both carried out, bilateral knee pass can also be disposably completed at the same time
Section scanning, right side knee joint scan select the channels R, left side knee joint scan that the channels L, bilateral knee joint is selected to scan simultaneously, together
When select L, the channels R.
Local coil system include coil upper piece 11, coil bottom sheet 12 and set on coil upper piece 11 and coil bottom sheet 12 it
Between two partition boards 14, be equipped with coil 13 in coil upper piece 11 and coil bottom sheet 12, the present embodiment coil 13 is annular.
