Specific embodiment
Technical scheme is specifically described with reference to embodiments, it is soft present invention is disclosed a kind of vertical magnetic resonance
Gonosome portion intervene special-purpose radio-frequency coil, as shown in Figures 1 to 5, including a broadband shape the flexible wires circle body for being around in human abdomen
5, connected by lock 72 after the two ends of flexible wires circle body 5 bending.
At least two visual windows are provided with the flexible wires circle body 5, five visual windows are provided with the present embodiment
51.Rigid circuit cover plate 6 is connected with the flexible wires circle body 5.Circuit board is provided with rigid circuit cover plate 6, in order to ensure
Circuit board not by backfin, using the circuit cover plate of rigid.The circuit cover plate 6 is arranged at intervals with two.
Specifically, the flexible wires circle body 5 includes a soft shell and the coil group being placed in soft shell.Flexible coil
Body 5 increased comfort level, meanwhile, preferably can be fitted with human abdomen, to be preferably imaged.
The coil group includes a " 8 "-shaped coil unit 1, and is partly overlapped setting with the " 8 "-shaped coil unit 1
Loop coil unit, and partly overlapped between the adjacent loop coil unit, the width of the loop coil is more than
The figure-eight coil unit, the loop coil unit is provided with 5.
The figure-eight coil unit is connected and composed by two ring antenna units are parallel, the antenna unit have and
There is an opening, two antenna element opening connections are formed with and have an intersection point, and when using, human body body is also cross two
The individual antenna element.
As shown in figure 3, respectively first annular coil unit 2, the second loop coil unit 3, the 3rd loop coil unit
4th, fourth annular coil unit, the 5th annular coil unit.The " 8 "-shaped coil unit is by two doroid unit portions
Divide and overlap.Above structure can obtain preferable coupling effect in the case where unnecessary decoupling circuit is not increased, several
Size identical loop coil cell-average is distributed in human peripheral and forms a circle so that signal is uniform, sensitivity and signal to noise ratio
Height, good imaging quality.
Because flexible shell is coated on outside the coil group, the annular mouth phase of the visual windows 51 and loop coil unit
When.In actual applications, the big I of visual windows 51 is configured according to coil inside spacing etc..Due to the trouble of some slight of statures
Person, can exist for coil to be supported to place well, and side is provided with dismountable gas in the flexible coil body
Capsule, when using, coil case is wrapped in human body waist and belly, and air bag is located between human body and coil case, and air bag is inflated to adjust
The size of whole air bag, accordingly even when patient's build is smaller, well can also support coil case, prevent coil from using
Rocked in journey, enhance the stability of image.Air cushion can be connected by bonding to buckle with the soft shell of coil case, it is also possible to logical
Other modes are crossed to be fixedly connected.In the case where precision of the present invention is ensured, body portion can be made to intervene coils special application more extensive.
The flexible wires circle body 5 restocking is provided with one is used to support the plate-shaped waist support 8 of human body.Because the support is general
For supporting human body, in order to have more preferable comfort level, the support has an arc plate face.Meanwhile, support is placed on sick bed
On, coil passes through support, that is, be placed between support and sick bed, and such patient lies onto sick bed, it is to avoid coil is compacted, line
Circle can also be twitched with respect to patient body longitudinal axis or so, so that perforate is positioned at patient and need to intervene the position of operation on coil
Put.
The further comfort level problem in view of user, is provided with dismountable negative in the arc plate face of the support
Pressure vacuum air cushion（Do not illustrate in figure）, when using, the negative-pressure vacuum air cushion is contacted with human body waist and belly.Specifically, described negative
Pressure vacuum air cushion is connected by thread gluing with arc plate face.Certain negative-pressure vacuum air cushion can also be fixed by other means.
The size of negative-pressure vacuum air cushion is configured according to the size of support plate face, when patient is lain on support, passes through
Negative-pressure vacuum air cushion is evacuated so that the filler inside negative-pressure vacuum air cushion is pressed against each other.Due to negative-pressure vacuum
It is filled using plastic particles in air cushion, when depressed, can be molded according to patient's bodily form, so as to form human body
Cavity plate, can not only improve the comfort level of user, meanwhile, also ensure that coil case fixed position when in use is not light
It is easily mobile, the precision of operation is improved indirectly.
The two ends of the flexible wires circle body 5 are provided with bindiny mechanism, and the bindiny mechanism includes being individually fixed in flexible wires
The connection end and fastening end at the two ends of circle body 5, the connection end are connected with the fastening end by lock 72.
The connection end is oriented to projection 91 and pilot hole 9, the guiding with also being provided with for selectivity on the fastening end
The side of projection 91 is provided with electric connection contact pin 74.Accordingly, the side of the pilot hole is provided with pin holes 73.
After on coil lock, in order to be further fixed, it is necessary to pass through outside bandage closer to patient.Specifically,
Being offered on the circuit cover plate can again be bound in connecting hole 61, the connecting hole 61 by bandage.
The present invention still has various specific embodiments.All use equivalents or equivalent transformation and all skills for being formed
Art scheme, all falls within the scope of protection of present invention.
