Section shortens sweep time, improves scan efficiency.
In order to achieve the above objectives, the technical solution adopted in the utility model is as follows:
Magnetic resonance Bilateral Symmetry joint while imaging coil, are opened including two local coil systems in parallel and control
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, is equipped with coil in coil upper piece and coil bottom sheet.
Further, coil bottom sheet is than coil upper piece softness.
Further, local coil system further includes two partitions set between coil upper piece and coil bottom sheet, and two
The setting of partition parallel interval, the lower end of partition and coil bottom sheet are affixed；
Coil upper piece side is connect with one of partition, the opposite other side of coil upper piece and another partition 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 partition of a local coil system and another
One of partition of one local coil system is affixed or integrally manufactured.
Wherein, coil is annular.
The detour shape alternatively, coil is in U-shape.
Further, coil channel has 4-6.
Compared with prior art, the utility model has the following beneficial effects:
The utility model can single-double dual-purpose, be suitable for the case where scanning single side or bilateral scan；Bilateral pair is scanned simultaneously
Claim joint, sweep time can be shortened, improves scan efficiency；Coil upper piece is flip structure, and the leg of patient is facilitated to put into and take out,
It is easy to use.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.
Embodiment one
As shown in Figure 1, the imaging coil simultaneously of magnetic resonance Bilateral Symmetry joint disclosed in the present embodiment, in parallel including two
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.Channel control switch can use letter L, R, and L represents left side joint, 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 channel R, and left side knee joint scan selects the channel L, and bilateral knee joint scans simultaneously, together
When select L, the channel R.
Local coil system include coil upper piece 11, coil bottom sheet 12 and be set to coil upper piece 11 and coil bottom sheet 12 it
Between two partitions 14, be equipped with coil 13 in coil upper piece 11 and coil bottom sheet 12, the present embodiment coil 13 is annular.
