Description
Technical field
The utility model is related to magnetic resonance imaging (MR+E) equipment technical field more particularly to a kind of head NMR zeugmatographic imagings
RF body coil.
Background technology
Magnetic resonance imaging (MRI) be according to have magnetic away from atomic nucleus under magnetic fields, transition between energy level can be generated
Principle and the new Examined effect used, MRI helps to check the energy state and brain blood flow situation of epileptic's brain, to becoming
Venereal disease diagnostic value is very big.
MRI is acted on by external high frequency magnetic field, is realized from substance in vivo to ambient radiation energy production signal,
Imaging process is close with image reconstruction and CT, and only MRI neither leans on extraneous radiation, absorption and reflection, does not also lean on radioactive material
The γ radiation of matter in vivo, but be imaged using the interaction of external magnetic field and object, high energy magnetic field is harmless.
Clinical common MRI checks the brain structure change for finding secondary epilepsy, if clinical classify not to epilepsy syndromes
Bright, MRI can specify the patient whether caused by brain structure changes, and intracranial tumors often cause epilepsy, and MRI is to intracerebral minuent star glue
The diagnosis confirmation rate of cell plastid tumor, neuromere, glioma, arteriovenous malformation and hemotoncus etc. is high.MRI can be clearly illustrated
The encephalatrophy of epileptic is fabulous to the display degree of brain parenchym and cerebrospinal fluid.
Magnetic resonance elastography (MRE) based on MRI imagings measures the bullet of brain tissue's (such as grey matter, white matter, tumour)
Property coefficient.With advancing age, the brain tissue of the elderly softens, the brain group of Alzheimer patient (senile dementia)
Softening is knitted, and the coefficient of elasticity of brain tumor is also different from normal cerebral tissue.
However be placed in patient mouthful the driver in existing MR+E inspections, patient starts to shake after being bitten with tooth. more
Dynamic imaging, then in this way so that patient comfort is greatly lowered, patient may be because uncomfortable and move, and cause mistaken diagnosis.
Therefore, it is necessary to provide a kind of new head NMR zeugmatographic imaging RF body coil.
