Embodiment approach ）

[0027] First, an example of the overall configuration of the MRI apparatus according to the present embodiment will be described. figure 1 It is a diagram for explaining an example of the overall configuration of the MRI apparatus according to the present embodiment. Such as figure 1 As shown, the MRI apparatus 1 according to this embodiment includes a gantry device 10 , a bed device 20 , and a control device 30 .

[0028] The gantry device 10 has a hole 11 as an imaging space for a magnetic resonance image (MRI image). And, while in figure 1 Although not shown in the figure, the gantry device 10 has a static field magnet for generating a static magnetic field inside the hole 11, a gradient magnetic field coil for generating a gradient magnetic field, and irradiates RF to the subject placed in the magnetic field generated by the static field magnet. Pulse sending RF coil, etc. In addition, depending on the gantry device 10 , there may be a receiving RF coil for receiving m...

Abstract

A magnetic resonance imaging apparatus of the present invention includes a gantry device, a front light source, and a cover as an external device of the gantry device. The gantry device has a hole serving as an imaging space for magnetic resonance images, and collects magnetic resonance signals from the subject while the subject placed on the top is moved into the hole by a bed device that moves the top. The front light source is provided at the opening of the hole and is located at the front opening of the bed apparatus, that is, the periphery of the front opening. The portion of the cover of the external device serving as the pedestal device that is irradiated with light irradiated from the front light source is formed of a transparent or translucent material.

Description

technical field [0001] Embodiments of the present invention relate to a magnetic resonance imaging apparatus and a medical image diagnosis apparatus. Background technique [0002] In imaging of an MRI image by a magnetic resonance imaging (MRI: Magnetic Resonance Imaging) apparatus, a subject is moved into a bore of a gantry device while being placed on a top plate. The gantry device generates a high-frequency magnetic field and a gradient magnetic field according to a pulse sequence corresponding to imaging conditions, thereby collecting magnetic resonance signals generated from a subject. [0003] The gantry device has a static field magnet for generating a uniform static magnetic field in the hole, a gradient magnetic field coil arranged inside the static field magnet for generating a gradient magnetic field in the hole, and the like. Static field magnets, gradient magnetic field coils, and the like are arranged outside a bore tube for securing a hole space. In addition...
