Embodiment 1

[0041] In order to solve the problem that volunteers 101 perform clinical medical examinations with head magnetic resonance imaging in upright, sitting or lying down positions, the present invention provides a full posture human head magnetic resonance imaging device, and also provides a full posture human body MRI device. Head magnetic resonance imaging method, which is based on computer synchronous control and adjustment of the lifting of the first multi-stage lifting platform column 1 and the second multi-level lifting platform column 12, so that the first permanent magnet and the magnetic yoke 5 and the second permanent magnet and the magnetic yoke 6 The upper and lower positions of the test bed 14 and the moving wheel 19 are adjusted together, so that the head 102 of the volunteer can be properly located in the magnetic fields generated by the first permanent magnet and the yoke 5 and the second permanent magnet and the yoke 6 In the central area, after shimming with the f...

Embodiment 2

[0067] A kind of head magnetic resonance imaging method of full posture human body, utilizes the head magnetic resonance imaging device of a kind of full posture human body described in embodiment 1, comprises the following steps:

[0068] Step 1. Synchronously control and adjust the first multi-stage lifting platform column 1 and the second multi-level lifting platform column 12 to rise so that the central area of ​​the magnetic field generated by the first permanent magnet and the yoke 5 and the second permanent magnet and the yoke 6 coincides with the The position of the volunteer's head 102 during the expected standing posture;

[0069] Step 2. Put the volunteer 101 on the folding examination bed 14, fasten the X-shaped adjustable fastening belt 10 and the adjustable fastening belt 11, adjust the height of the lifting pedal 15, and adjust the horizontal / upright electric rotation unit 16 , so that the examination bed 14 is folded to an upright state, at this time, the volunte...

Abstract

The invention discloses an all-posture human body head magnetic resonance imaging device, which comprises two multi-stage lifting platform columns. The device further comprises a reverse concave frame, a first permanent magnet and magnet yoke, a second permanent magnet and magnet yoke, two compensation coils, two gradient coils, a head coil, two adjustable fastening belts, an adjustable folding adjusting frame, a folding examination bed, a lifting pedal, a horizontal/vertical electric rotating unit, an electric lifting platform column, a balance plate and moving wheels. The invention further discloses a head magnetic resonance imaging method of the all-posture human body, through synchronous control and height adjustment of the two multi-stage lifting table columns, the vertical positions of the first permanent magnet and the magnet yoke and the vertical positions of the second permanent magnet and the magnet yoke are changed, the height of the folding examination bed is correspondingly changed, and head magnetic resonance imaging of the standing posture, the sitting posture and the lying posture of the human body can be achieved. Therefore, the change of cerebral blood flow, structure and function of the all-posture human body under the action of gravity is known, the detection function of the magnetic resonance imaging device is expanded, and the magnetic resonance imaging device is convenient and practical and has important medical clinical application value.

Description
