Abstract
The invention relates to an assistant device for magnetic resonance scans of a knee joint. The assistant device is a rectangular flat shaped bottom plate, wherein vertical side baffle plates are respectively connected to the two sides of the bottom plate, and the inner side surfaces of the side baffle plates are parallel to each other; and an included angle between the inner side surfaces of the side baffle plates and the bottom plate is 70 to 75 degrees. By adopting the assistant device for magnetic resonance scans of the knee joint, the defects of a knee joint magnetic resonance scans positioning method and the motion artifact caused by the heteronomous moving of an examined person are effectively overcome,, the success rate of single scans is increased, the number of scans is reduced, and the paint of the examined person is relieved.
Description
Technical field
The present invention relates to fixedly auxiliary device of a kind of human body that is used for magnetic resonance imaging, especially a kind of assistance device that is used for the knee joint magnetic resonance imaging.
Background technology
The inspection of existing knee joint requires knee joint abduction 15 degree ~ 20 degree more, makes the anterior cruciate ligament orientation parallel with the sagittal scan direction, makes the patient put by the technician that parallactic angle degree maintenance knee is motionless to be accomplished to magnetic resonance examination; But because the magnetic resonance examination time is longer; Patient's pathologic changes of knee joint pain can't be stood long magnetic resonance examination, and knee joint is not independently moved; Thereby cause the pseudo-shadow of corresponding sports many, influence the accuracy rate of check result.
Summary of the invention
In order to address the above problem; The present invention proposes a kind of assistance device that is used for the knee joint magnetic resonance imaging; The defective and the person under inspection that have overcome knee joint magnetic resonance pendulum method for position effectively independently do not move the motion artifacts that causes; Improve the success rate of single sweep operation, reduced the number of times of scanning, alleviated person under inspection's misery.
The technical solution adopted for the present invention to solve the technical problems is: this assistance device that is used for the knee joint magnetic resonance imaging comprises base plate and side shield; Said assistance device has a rectangular tabular base plate; The both sides of this base plate are connected with vertical side shield respectively; The medial surface of said side shield is parallel to each other, and the medial surface of side shield and the angle between the base plate are 70 degree ~ 75 degree.
The medial surface of said side shield and the angle between the base plate are preferably 72 degree.
Internal diameter horizontal distance W between said two side shields is 12 cm ~ 16cm, is preferably 14 cm; The vertical height H of said side shield is 16 cm ~ 20cm, is preferably 18cm.
The invention has the beneficial effects as follows: this is used for the assistance device of knee joint magnetic resonance imaging; The defective and the person under inspection that have overcome knee joint magnetic resonance pendulum method for position effectively independently do not move the motion artifacts that causes; Improved the success rate of single sweep operation; Reduce the number of times of scanning, alleviated person under inspection's misery.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Accompanying drawing 1 is used for the example structure sketch map of the assistance device of knee joint magnetic resonance imaging for this.
Among the figure, 1. base plate, 2. side shield.
The specific embodiment
In the accompanying drawings, this assistance device that is used for the knee joint magnetic resonance imaging comprises base plate 1 and side shield 2; Said assistance device has a rectangular tabular base plate 1; The both sides of this base plate 1 are connected with vertical side shield 2 respectively; The medial surface of said side shield 2 is parallel to each other, and the angle between the medial surface of side shield 2 and the base plate 1 is 70 degree ~ 75 degree.
Angle between the medial surface of said side shield 2 and the base plate 1 is preferably 72 degree.
Internal diameter horizontal distance W between said two side shields 2 is 12 cm ~ 16cm, is preferably 14 cm; The vertical height H of said side shield 2 is 16 cm ~ 20cm, is preferably 18cm.
When carrying out the knee joint scan inspection; With outer screen 15 degree of patient's knee ~ 20 degree; And the foot that makes the patient stretches in this auxiliary device, because the angle of inclination of the medial surface of the side shield 2 of this auxiliary device is consistent with the kneed abduction angle of patient, can help patient's better maintenance knee joint start point in checking process constant; Prevent the generation of pseudo-shadow, improved the accuracy of inspection.
This assistance device that is used for the knee joint magnetic resonance imaging is two one group, and the incline direction of its side shield 2 medial surface is opposite, is respectively applied for the fixing of left lower limb and right lower limb.
