Rapid development through physiology and Cognitive Neuroscience.In nuclear magnetic resonance check, when inspection, can generate biggish noise, this is made an uproar
Caused by sound is the current high speed switch checked in equipment in gradient magnetic field coil.When nuclear magnetic resonance, in order to generate gradient magnetic,
Need in coil through electric current, since coil itself is in magnetic field, so once be powered coil will stress, and MRI
Electric current in these coils of job requirement is opened and closed with high speed, therefore will cause the high-frequency vibration of coil, the height
Frequency vibration just makes patient perceptions to huge noise.And noise is excessive, then is easy that patient's brain is made abnormal active region, shadow occur
The judgement of examiner and clinician to treatment or action of scientific research is rung, therefore, accuracy is checked to improve, nuclear-magnetism should be reduced as far as possible
The noise generated in resonance checking process.Since the noise is and the nuclear magnetic resonance check as caused by nuclear magnetic resonance check equipment
Equipment price is high, thus in the case where being changed without nuclear magnetic resonance check equipment, and noise when inspection is inevitable.
And in order to reduce noise as far as possible, then the noise that patient perceptions arrive can only be reduced by external auxiliary measure, improve inspection environment.
Currently, cotton or earplug can be prepared in nuclear magnetic resonance check room to patient, play certain soundproof effect, but soundproof effect compared with
Difference, and cotton or earplug plug stability in ear are poor, may fall.
