Description

TECHNICAL FIELD

[0001] The utility model relates to medical auxiliary appliance technical field especially a kind of magnetic resonance shoulder joint coil fixing device and magnetic resonance imaging system. BACKGROUND

[0002] Magnetic resonance (MR) imaging itself is a relatively slow process, in order to obtain detailed images, often need longer scanning time, and due to the principle of magnetic resonance technology, the corresponding coil needs to be close to the examination site to obtain better signal-to-noise ratio. Especially for shoulder joint, such as deviating from the center of the body axis and easily affected by respiratory movement, the coil shape design, fixing method and use material are very particular, not only to consider various body type population, but also to consider the comfort of the examinee and the actual examination site, and more need to consider the special fixing method of part of the severely damaged shoulder joint.

[0003] And the current market MR manufacturers shoulder joint coil design is mainly divided into two categories: the first type is L type hard coil ( Figure 1 ), this product is compatible with large body type population, and the size cannot be made very small, which will cause the fitting problem of small body type population, so that the shoulder joint of the examinee with small body and thin body thickness cannot be well fitted with the coil, and it is difficult to realize the central fitting, and the hard material often has the comfort problems of neck jamming or shoulder pressing. The second type is long strip-shaped flexible coil ( Figure 2 ), the common problem of this type of product is the fitting problem from the shoulder peak to the neck, and the current most solutions are to wrap the part exceeding the shoulder peak, but it does not fundamentally solve the problem. Once the coil fitting degree is not good or the coverage area has deviation, it will have great influence on image quality, such as causing signal-to-noise ratio to decrease, examination time to be prolonged, motion artifacts caused by examinee discomfort, uneven fat suppression, etc. The fixing of the two types of coils is generally through the binding around the examinee's body, and the fixing method is usually complex, so as to cause the low examination efficiency of hospital and poor experience of examinee.
