摘要： A cooling unit operating in a magnetic field is provided. The cooling unit includes an encasement body having a non-electrically conductive composition and defining a first and second opposing planar surface. The cooling unit also includes a metal conduit disposed in the encasement body substantially parallel to the first surface. Additionally, the cooling unit also includes a series of metal fins disposed in the encasement body and extending from the conduit. In some configurations the fins can be substantially parallel to the first surface. Further, in some configurations, non-electrically conductive inserts having a thermal conductivity greater than a thermal conductivity of the encasement body can be disposed in a portion of the encasement body between one of the first and second surfaces and one or more of the metals fins.

摘要： The present embodiments provide a gradient coil assembly. The gradient coil assembly includes an aluminum wire body, and a copper wire end connected by cold pressure welding to two ends of the aluminum wire body. Using the gradient coil according to a particular embodiment, it is possible to reduce gradient coil weight as well as reduce the thickness of an outer vacuum chamber used for a magnet, thereby reducing the cost of the magnet and gradient coil, and making it less difficult to install and maintain the magnet and gradient coil. There is no problem of oxidation associated with the cold pressure welding of the aluminum wire body to the copper wire ends, so quality defects arising from such oxidation are avoided.

摘要： A medical imaging apparatus includes a first imaging modality which is formed by a magnetic resonance apparatus and which comprises a cylindrical gradient coil unit, and a further imaging modality which comprises a detector unit. The detector unit of the further imaging modality is supported in a radial direction within an area surrounded by the gradient coil unit and an annular gap is disposed between the detector unit of the further imaging modality and the gradient coil unit. The further imaging modality includes a pressure unit which is disposed in the annular gap between the detector unit of the further imaging modality and the gradient coil unit.

摘要： An arrangement for connection of gradient current feed lines in a magnetic resonance apparatus has an electrically insulating connection plate with at least one connection device. The connection device is fashioned to electrically connect a first gradient current feed line with a second gradient current feed line and is associated with a gradient coil that forms a gradient field via a supplied gradient current for a spatial direction. The supply ensues via the two gradient current feed lines connected with one another. A base plate that is fashioned for fastening the connection plate to a magnet housing of the magnetic resonance apparatus. An electrically insulating layer to damp vibrations of the connection plate is arranged between the base plate and the connection plate.
