Fixing device for magnetic resonance inspection

Abstract

The invention discloses a fixing device for magnetic resonance inspection. The fixing device comprises a bed body and a head fixing device, wherein a headrest is arranged on the front end surface of the bed body; the head fixing device comprises two sliding plates oppositely arranged on the left and right sides of the headrest as well as driving mechanisms used for driving the two sliding plates to do relative motion; earmuffs used for fixing the head of an inspected person and blocking two ears are arranged the opposite inner sides of the two sliding plates respectively. By means of the technical scheme, the two sliding plates are driven by the driving mechanisms to get close to each other, so that the earmuffs on the two sliding plates abut against the double ears of the inspected person, and accordingly, the head of the inspected person is fixed; besides, ear canals of the inspected person are sealed by the two earmuffs, the condition that the inspected person moves restlessly underthe influence of noise is avoided, the quality of magnetic resonance imaging scanned pictures is guaranteed, the speed of magnetic resonance inspection is increased, and the work difficulty of medical workers is reduced.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a magnetic resonance examination fixing device. Background technique [0002] Clinically, when the cervical spine MRI examination is performed on the examiner, the examiner needs to be in a supine position. Due to the softness of the headrest on the bed, the position of the cervical spine is prone to shift if the examiner moves slightly, resulting in a decrease in the quality of the scanning image. Loud noise will be generated at the beginning of the scan, and the patient is prone to restlessness and move his body in this noise environment, which will cause the shaking of the head and cervical spine and cause scanning motion artifacts, which will greatly reduce the quality of image diagnosis and greatly reduce the inspection time. speed. Contents of the invention [0003] The object of the present invention is to solve the deficiencies in the prior art at least to a...
