Abstract: A catch device and a shell liner for a medical imaging apparatus and a magnetic resonance imaging (MRI) apparatus that has an elastic arm, the elastic arm having a clamping portion, two bending portions located on two sides of the clamping portion and two end portions formed by extension of the ends of the two bending portions away from the clamping portion, the two end portions being used for being fixed to a liner of the first shell; and at least one roller, the roller being rotatably sheathed on the clamping portion of the elastic arm and clamping an edge of the second shell to the liner of the first shell by using an elastic force of the elastic arm, and an axial direction of the roller is parallel to the liner of the first shell and the edge of the second shell. The catch device achieves a simple and firm connection between apparatus shells, and meets requirements for a pleasing appearance and convenient application and maintenance.

Abstract: A phantom for an MRI system is provided. The phantom includes a third layer, the third layer including a first structure and a second structure, the first structure including two adjacent wedge-shaped objects in opposite directions which do not generate magnetic resonance signals, the second structure includes a first module group pair, the first module group pair including a first module group and a second module group, the first module group and the second module group each including multiple modules which are identical to each other, aligned with each other and separated from each other by the same distance, and the first module group and the second module group are perpendicular to each other. The phantom for an MRI system can satisfy measurement of multiple image quality indices such as layer thickness and resolution at the same time, which saves a large amount of repetitive work and time.

Abstract: A connector and medical equipment are provided. The connector includes at least one framework and at least one fastening structure. The at least one connector is used to connect a main body and a housing. The at least one framework is arranged along the outside of the main body. The fastening structure is located on the at least one framework. The at least one fastening structure is used to connect the housing.

Abstract: A lighting device for an MRI system aperture has at least one LED lamp and a light guide plate, the light guide plate having an interior surface, an exterior surface and multiple end faces. The end faces include a first end face, a second end face and one or more other end faces. Light rays from the LED lamp enter the light guide plate through the first end face, and exit the light guide plate through the exterior surface. The inner surface is opposite the outer surface, and the second end face is opposite the first end face. This lighting device for an MRI system aperture reduces the volume occupied in the MRI system aperture and at the same time the light rays are gentle and produce an effect of gradual change, protecting the examination subject's eyes and dispelling nervous feelings and claustrophobia in the examination subject.

Abstract: An MRI apparatus and a bed board assembly with illumination are described. The MRI apparatus includes: a frame with a cavity; a support rail disposed in the cavity; a bed board, which enters or exits the cavity moveably via the support rail; and an illumination unit disposed in a front portion of the bed board, for emitting light to provide illumination when the MRI apparatus is performing a scan. Space inside the cavity may be saved, and an examination subject may have the impression of being in a more open and brighter space, alleviating the subject's discomfort or fear effectively.
