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 antennas, wherein each of the two antennas is designed as a J-pole antenna with a radiation section and a feed section. The radiation sections of the two antennas are arranged crossing each other. In this way, effective decoupling of the antennas is achieved by simple means.
Claims20
An antenna assembly for an imaging method, the antenna assembly comprising
- at least two antennas, each of the two antennas configured as a J-pole antenna with a radiation section and a feed section,
- wherein the radiation sections of the two antennas are arranged crossing each other, and wherein the antenna assembly is an antenna assembly for magnetic resonance imaging (MRI), ultra-high field MRI, MR positron emission tomography (MR-PET), MR single proton emission computed tomography (MR-SPECT), MR linac and/or MR ultrasound.
A method of using an antenna assembly in a tomography system, the method comprising
- providing the antenna assembly having at least two antennas, each of the two antennas configured as a J-pole antenna with a radiation section and a feed section, wherein the radiation sections of the two antennas are arranged crossing each other, 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 antennas, each of the two antennas configured as a J-pole antenna with a radiation section and a feed section, wherein the radiation sections of the two antennas are arranged crossing each other, and wherein the antenna assembly is arranged in particular such that the feed sections are located outside a measuring range of the tomography system.
