20100010337 | Combined PET/MRI device, component and local coil - A combined PET/MRI device is disclosed. In at least one embodiment, the PET/MRI device includes an MRI unit for exciting nuclear spins in an examination volume and for receiving signals generated by the excitation in the examination volume, and a PET unit with a detector which surrounds the examination volume at least in part and is used for detecting radiation emanating from the examination volume, with, firstly, damping of the radiation emitted by the examination volume and, secondly, undesired interactions with electromagnetic fields of the MRI unit on the components of the PET/MRI device arranged between the examination volume and the detector being avoided due to the material properties and/or structural design of the components. Corresponding components such as, for example, patient couches, bearing or support apparatuses and local coils, are both MRI and PET compatible. | 01-14-2010 |

20130090896 | METHOD FOR DETERMINING AN OPTIMAL STRUCTURE OF A HIGH-FREQUENCY SHIELD OF A HIGH-FREQUENCY ANTENNA OF A MAGNETIC RESONANCE ARRANGEMENT - A method determines an optimal structure of a high-frequency shield of a high-frequency antenna of a magnetic resonance arrangement. The high-frequency shield shields the high-frequency antenna from a gradient-coil arrangement. A three-dimensional initial structure of the high-frequency shield is defined in accordance with structural parameters and jointly with the high-frequency antenna, the gradient-coil arrangement, or both the high-frequency antenna and the gradient-coil arrangement. The structural parameters are optimized via an optimization method with respect to at least one optimization criterion. | 04-11-2013 |
20130127463 | Magnetic Resonance Antenna Arrangement and Magnetic Resonance System - A magnetic resonance antenna arrangement includes at least one first antenna group including individually-controllable first antenna conductor loops and a second antenna group adjacent to the first antenna group. The second antenna group includes individually-controllable, longitudinal second antenna elements. The first antenna conductor loops essentially extend in a first extending surface and are disposed in the first extending surface in a first direction in a row behind one another. The longitudinal second antenna elements extend with the longitudinal axes transverse to the first direction disposed in parallel next to one another in a second extending surface that runs essentially in parallel to the first extending surface. Each of the second antenna elements are coupled at first and second end areas to a conductive element to form a second conductor loop with the conductive element. The second antenna elements are disposed to overlap an adjacent first antenna loop in each case. | 05-23-2013 |
