Abstract
The present disclosure relates to an antenna assembly for an imaging method, a use of an antenna assembly and a tomography system, in particular for MRI or simultaneous MR-PET/SPECT. An antenna assembly for an imaging method comprises at least two adjacent antennas, wherein each of the at least two antennas is designed as a J-pole antenna with a radiation section and a feed section. The at least two antennas are arranged alternately at a first angle and a second angle different from the first angle in relation to a reference surface. In this way, effective decoupling of the two antennas is achieved by simple means.
Claims19
An antenna assembly for an imaging method, the antenna assembly comprising
- at least two adjacent antennas, wherein each of the at least two antennas is configured as a J-pole antenna with a radiation section and a feed section,
- wherein the at least two antennas are arranged alternately at a first angle and a second angle different from the first angle in relation to a reference surface, and
- wherein the antenna assembly comprises at least three antennas which are designed as J-pole antennas and are arranged alternately at the first angle and the second angle in relation to the reference surface.
A method of using an antenna assembly in a tomography system, the method comprising
- providing the antenna assembly having at least two adjacent antennas, wherein each of the at least two antennas is configured as a J-pole antenna with a radiation section and a feed section, and wherein the at least two antennas are arranged alternately at a first angle and a second angle different from the first angle in relation to a reference surface, and
- acquiring imaging via MRI or simultaneous MR-PET/-SPECT using the antenna assembly.
A tomography system, adapted for MRI or simultaneous MR-PET/SPECT, the system comprising an antenna assembly having at least two adjacent antennas, wherein each of the at least two antennas is configured as a J-pole antenna with a radiation section and a feed section, and wherein the at least two antennas are arranged alternately at a first angle and a second angle different from the first angle in relation to a reference surface, and wherein the antenna assembly is arranged in particular such that the feed sections are located outside a measuring range of the tomography system.
