Title:
計算機式断層写真システムにおける高データ速度通信用の位相分割器を用いた伝送線路
Document Type and Number:
Japanese Patent JP3693347
Kind Code:
B2
Abstract:
A computerized tomography (CT) system includes a stationary frame, an annular rotating frame and apparatus that includes a phase splitter having an input port coupled to receive a modulated carrier having a relatively wide bandwidth. The phase splitter has first and second output ports for supplying, respectively, first and second modulated carrier constituents having a uniform phase angle differential, such as 180 DEG , between one another while maintaining a uniform amplitude over the bandwidth for the modulated carrier. A transmission line is attached to the rotating frame and is positioned around the annular rotating frame. The transmission line comprises one or more individual segments having first and second conductors respectively coupled to the output ports of the phase splitter to receive the first and second modulated carrier constituents from the phase splitter. A coupler is attached to the stationary frame and is positioned sufficiently near the transmission line for establishing radio coupling therebetween to receive the first and second modulated carrier constituents being applied to any of the individual segments.
