Background
Magnetic resonance, also known as magnetic resonance imaging, spin imaging, nuclear magnetic resonance imaging, is a significant improvement in medical imaging following CT. Since the 80 s of application, it has developed at an extremely rapid rate. The basic principle is that the human body is placed in a special magnetic field, and when the measured object is placed in the magnetic field, the hydrogen atoms in the human body can be polarized. Radio frequency pulses are used to excite hydrogen nuclei in the human body, causing the hydrogen nuclei to resonate and absorb energy. After the radio frequency pulse is stopped, the hydrogen atomic nucleus sends out radio signals according to specific frequency, releases absorbed energy, is recorded by a receiver outside the body, and is processed by an electronic computer to obtain an image.
MRI provides not only a greater amount of information than many other imaging procedures in medical imaging, but also differs from existing imaging procedures, and thus has great potential advantages for the diagnosis of disease. Because it can directly make the cross section, sagittal plane, coronal plane and various inclined plane body layer images; and has no ionizing radiation and no adverse effect on the body, and thus is increasingly used in the medical field.
The radio frequency coil is an important component of a magnetic resonance imaging system and is used for generating radio frequency pulses to excite a scanned object and generate magnetic resonance signals; then, the radio frequency coil receives the magnetic resonance signal, and 2D or 3D images of the scanned object are obtained through subsequent data processing. In order to better acquire the magnetic resonance signal of the scanned part and improve the signal-to-noise ratio of the image, the local coil is widely applied. Local coils are often designed for a particular scanned area, such as for the ankle, the wrist, the spine, the head, etc.
In the prior art, when scanning a head image, in order to prevent the head of a patient from moving, the head of the patient needs to be padded by a fixture on the inner side of a head coil. But at present there is not the fixing device of standard, only use simple and easy devices such as foam-rubber cushion to fix patient's head clinically, this kind of simple and easy fixed mode is easy not hard up, and fixed effect is relatively poor, leads to patient's head skew in the scanning process, seriously influences imaging quality, and simple and easy fixing device such as foam-rubber cushion that uses clinically fixes the effect relatively poor, can not restrict patient's head removal in the scanning process betterly, and does not have corresponding adjusting device moreover, can not adjust according to patient's head size or size.
