摘要： An electrical circuit with one or more semiconductor components (10) is characterized in that at least one semiconductor junction of at least one of the semiconductor components of the electrical circuit is disposed such that the average direction of motion of the charge carriers in the semiconductor junction is essentially parallel to the lines of force of the magnetic field B0, wherein the corresponding semiconductor component is disposed directly on a substrate (12), which is made of a material with good thermal conduction properties. In this way, undistorted characteristics of the semiconductor component used can be ensured despite the very strong magnetic field and the low operating temperatures.

摘要： A magnetic resonance imaging (MRI) apparatus suitable for radiotherapy. The apparatus includes two sets of coil pairs, each coil pair forming a Maxwell-like coil. The two sets of coil pairs share a common transverse plane, have opposing polarities, and define a common plane of symmetry and an imaging area. The two sets generate a substantially homogenous electromagnetic field in a first transverse direction in the imaging area and peripheral electromagnetic fields in a direction opposite to the first transverse direction in a peripheral area. The apparatus also includes at least one focusing magnet positioned in the peripheral areas to generate a focusing electromagnetic field in a focusing area, in a direction substantially the same as the first transverse direction. At least a portion of the peripheral electromagnetic fields is maintained in a defocusing area between the focusing area and the imaging area.
