Embodiment:
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Fig. 1 is the structural representation of knee coil of the present utility model; Fig. 2 is the structural representation that includes the knee coil of fill-in pad of the present utility model.
Please refer to Fig. 1 and Fig. 2, the knee coil that the utility model provides, comprise compliant member 2, hard material drain pan 1, the bottom of compliant member 2 is connected with hard material drain pan 1, compliant member 2 includes internal conductor layer with hard material drain pan 1, not shown, the internal conductor layer of the internal conductor layer of compliant member 2 and hard material drain pan 1 electrically conducts, and compliant member 2 tops are provided with link 3.
Hard material drain pan 1 is duroplasts structure, conventionally adopts the moulding processs such as mold injection or resin-cast to manufacture.1 pair of knee coil of hard material drain pan has played good supporting role, can realize the flexible positioning of knee coil and remove.Compliant member 2 is two-piece type symmetrical structure, and two bottom combines with hard material drain pan, can be by withholding, inlay, screw connects and bonding in any one mode link into an integrated entity.Compliant member 2 is made for elasticity macromolecular material, as artificial Elastic plastic-rubber or foamed plastics, can adopt the technological formings such as mold injection, cast or hot pressing, also can adopt synthetic leather or natural leather to make and form as covering.When patient is carried out to magnetic resonance imaging, compliant member 2 bendings are to be coated on patient's knee surface, and the use of flexible material has improved patient's comfort and tolerance.Hard material drain pan 1 and compliant member 2 include internal conductor layer, and this internal conductor layer is specially the circuit for knee coil.During the internal conductor layer of the internal conductor layer of compliant member 2 and hard material drain pan 1 can be connected with screw by welding, riveted joint, jump ring, thereby any one mode connects to realize and electrically conducts.
The top of compliant member 2 is provided with link 3.Compliant member 2 tops disconnect, at disconnection position, link 3 is set, join with the two ends at compliant member 2 disconnection positions respectively, can adopt withhold, inlay, screw connects is connected with any one mode in bonding, the free end of link 3 overlaps on together, can connect or screw connection for buckle.It is a kind of that to be preferred embodiment link 3 make for hard material.The free-ended overlapping area of adjusting link 3 can change the internal diameter of knee coil, and knee coil and patient's knee position are fitted tightly, and has improved the signal to noise ratio of radiofrequency signal.On link 3, be provided with engraved structure 4, corresponding to human knee protruding part, be preferably engraved structure 4 is designed to circle.When patient is carried out to MRI scan, knee coil need to be coated on knee surface, special tectonic due to human knee position, at the outstanding position of knee, patient can not feel well because coil is coated, in order to improve this situation, position corresponding to human knee's projection on knee coil arranges engraved structure 4, make to lean out in the projection engraved structure 4 of knee, arranging of engraved structure 4 meets base of principle of human engineering, improved patient's comfort and tolerance.
Before magnetic resonance examination starts, while arranging knee coil for patient, utilize hard material drain pan 1 that knee coil is accurately fixed on examination couch, then open the free end of link 3, compliant member 2 bendings are to be coated on patient's knee surface, regulate the free-ended overlapping area of link 3, knee coil and patient's knee surface is fitted tightly, finally lock two free ends of link 3, knee coil is fixed on to patient's knee surface, with relatively moving between the knee coil avoiding may occurring in scanning process and patient's knee position.
The adjustable extent of two free-ended overlapping areas of link 3 is limited, for the patient of build slight of stature, even by overlapping rea adjusting to maximum, also cannot make knee coil and patient's knee surface fit tightly.In order to address this problem, can fill-in pad 5 be set in compliant member 2 inner sides, it between fill-in pad 5 and compliant member 2, is detachable connection, according to different patients' needs, select whether in compliant member 2 inner sides, fill-in pad 5 is set and several fill-in pads 5 are set, to reach the effect that knee coil and patient's knee surface are fitted tightly.
In sum, the knee coil that the utility model provides and MR imaging apparatus, top at knee coil arranges the link that includes engraved structure, patient is when carrying out MRI of knee scanning, knee protruding part can lean out in engraved structure, has improved patient's comfort and tolerance; In knee coil compliant member inner side, fill-in pad is set, causes knee coil and patient's knee surface to fit tightly, avoided contingent relatively moving between knee coil and patient's knee position, improved picture quality.
Although the utility model discloses as above with preferred embodiment; so it is not in order to limit the utility model; any those skilled in the art; within not departing from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection range of the present utility model is worked as with being as the criterion that claims were defined.
