Rotary unit with a device for wireless data transmission between the two relatively movable parts, as well as a method for wireless data transmission between two relatively movable parts

摘要

The present invention relates to a device for wireless data transmission as well as a method for wireless transmission of data between two relatively moving parts of a medical imaging device. Such a medical imaging device comprises a rotating unit with two relatively movable parts as well as a device for wireless transmission of the measuring - and / or operating data between the movable parts. In this case, the device has at least one first communication device comprising at least one transmitter to the mail item of at least one high-frequency signal, a second communications device comprising at least a receiver unit for receiving at least of a high-frequency signal, wherein the first and second communication devices to the different parts of the rotary unit are arranged, and a directional coupler comprising at least two transmission cables, whereby one of the high-frequency lines at one end is connected with the first communication device and at the other end is closed off in a real fashion, wherein the second high frequency line with the second communications device is connected, and wherein one of the high-frequency lines at least in a ring around the complete circumference of one of the two relatively movable parts of the rotary unit 1 while the other high frequency line extends to at least a portion of the circumference of the other part of the rotary unit is arranged in such a way that a constant power output from the with the communications device comprising at least one transmitter unit is connected to the high frequency line can be coupled out.
