Abstract
In a mammography antenna arrangement for magnetic resonance examinations of a female breast, a conductor arrangement forms a closed circuit and surrounds a receptacle opening for the female breast. The receptacle opening lies in a surface that is essentially horizontally directed. Two arcuate conductor segments have their ends connected to the conductor arrangement via electrical connecting locations and surround an examination space that is fashioned for the acceptance of the female breast. The two conductor segments are respectively arranged in vertical, planes, the two planes being perpendicular to one another.
Claims20
A mammography antenna arrangement for conducting a magnetic resonance examination of a female breast comprising:
- first and second arcuate conductors, each arcuate conductor having ends and a zenith between said ends;
- a further conductor, said further conductor forming a closed circuit and defining a receptacle opening, said ends of said first and second arcuate conductors being electrically connected to said further conductor and adapted to receive a female breast when inserted in said receptacle opening, said first and second arcuate conductors being connected to said further conductor at respective junctions successively disposed along said further conductor with said arcuate conductors respectively disposed in different planes, said planes being disposed perpendicularly to each other, said arcuate conductors being identical and each lying symmetrical about a symmetry axis, said arcuate conductors, being connected to said further conductor with their respective symmetry axes coinciding;
- a plurality of capacitors connected in said further conductor with at least one capacitor disposed between each pair of successive junctions;
- a first signal terminal connected across a first of said capacitors;
- and
- a second signal terminal connected across a second of said capacitors, said first and second capacitors sharing a common one of said junctions and said first and second signal terminals being decoupled from each other.
