Abstract: A medical instrument for magnetic resonance imaging guided radiotherapy includes a magnetic resonance imaging system for acquiring magnetic resonance data from an imaging zone, a radiation source for emitting X-ray or gamma ray radiation directed at a target zone within the imaging zone, wherein the radiation from the radiation source directed to the target zone passes through a radiation window of the magnetic resonance imaging system. The magnetic resonance imaging system includes at least one radiation transparent electrical transmission line, which is configured for transmitting an electrical signal and which extends through the radiation window, wherein the electrical transmission line is provided by a microstrip comprising a conductor line extending parallel to the ground layer, wherein the conductor line and the ground layer are separated from each other by a dielectric substrate.

Abstract: The invention relates to a device (34) for an MRI apparatus (14), especially an MRI apparatus (14) of an MR guided radiation therapy system (10), the device (34) comprising at least one MR imaging marker unit (72), wherein the marker unit (72) comprises an at least slightly MR-visible film (70) covering at least one conducting part of an electrical circuit loop (68) of the device (34). The invention further relates to the corresponding MRI apparatus (14) and MR guided radiation therapy system (10).

Abstract: A method for managing routing information in a communications system comprises-defining, in a client network apparatus, a unique private IP address, the unique private IP address uniquely identifying a terminal and the corresponding remote network. The client apparatus defines an IP routing address for the remote network. The client apparatus routes a data packet to a VPN tunnel having the IP routing address defined for the remote network, the data packet being directed to the remote network identified by the unique private IP address. The unique private IP address is translated into a corresponding customer IP address of the terminal in order the data packet to be routable to the terminal in the remote network.
