Abstract
A dipole antenna array includes at least two dipole antenna elements. Each respective dipole antenna element has at one end a fold which consists of a bend, a bent region, and the projection of the bent region of the dipole antenna element onto a length of the dipole antenna element. Each respective dipole antenna element at least partially encloses a cavity.
Claims15
A dipole antenna array comprising:
- at least two J-shaped dipole antenna elements, each respective J-shaped dipole antenna element comprising a first length, a second length, and at least one bend connecting the first length to the second length, wherein the first length is longer than the second length, wherein a fold is formed that comprises the at least one bend, the second length, and a projection of the second length onto the first length, and
- wherein the at least two J-shaped dipole antenna elements at least partially enclose a cavity.
A method for magnetic resonance-positron emission tomography (MR-PET) or magnetic resonance-single photon emission computed tomography (MR-SPECT) tomograph, comprising:
- providing a dipole antenna array, the dipole antenna array comprising:
- at least two dipole antenna elements, wherein each respective dipole antenna element has at one end a fold which consists of a bend, a bent region, and the projection of the bent region of the dipole antenna element onto a length of the dipole antenna element,
- wherein each respective dipole antenna element at least partially encloses a cavity,
- wherein folds of the dipole antenna elements with connections are located outside a PET or SPECT measurement region.
A magnetic resonance-positron emission tomography (MR-PET) or magnetic resonance-single photon emission computed tomography (MR-SPECT) tomograph, comprising:
- a dipole antenna array, comprising:
- at least two dipole antenna elements, wherein each respective dipole antenna element has at one end a fold which consists of a bend, a bent region, and the projection of the bent region of the dipole antenna element onto a length of the dipole antenna element,
- wherein each respective dipole antenna element at least partially encloses a cavity, and
- wherein folds of the dipole antenna elements with connections are located outside a PET or SPECT measurement region.
