摘要： An antenna unit for a PET/MRI scanner is disclosed, including a supporting tube in which at least one antenna for MR signals is arranged. In at least one embodiment, the supporting tube has at least one permeable section and one impermeable section, the permeable section of which has a greater permeability to PET quanta than the impermeable section. The antenna unit further includes a screen for radio-frequency signals which is arranged outside of the supporting tube and surrounds the latter. In at least one embodiment, an intermediate layer is arranged between the supporting tube and the screen and, in the region of the permeable section of the supporting tube, is composed of, at least in part, a material which has a permeability to PET quanta comparable to the permeable section.

摘要： In a gradient coil and a method to manufacture a gradient coil for a magnetic resonance apparatus, the gradient coil has at least one saddle coil, the saddle coil having a spatially shaped, electrically conductive plate with a line-shaped recess penetrating the plate. Conductor structures that create a gradient magnetic field in an examination region when a current signal flows therethrough are formed by the recess and by the shaping of the plate. The recess is filled with an electrically insulating material before implementation of the spatial shaping.

摘要： A device is disclosed for superposed magnetic resonance and positron emission tomography imaging. In at least one embodiment the device includes a gradient coil and a positron emission tomography unit (PET unit). The PET unit is arranged within the gradient coil and has a first shield against radiofrequency radiation which in part surrounds the PET unit, and a second shield against radiofrequency radiation is arranged on the gradient coil. The first shield is connected to the second shield to form a shield which is at least partly closed. This makes a closed shield for the PET unit possible, which nevertheless is still easily accessible for maintenance purposes due to the two-part design of the shield.
