Abstract
In an antenna arrangement for a magnetic resonance apparatus and a method for acquiring magnetic resonance signals, which has at least four individually operable antenna conductor loops arranged like a matrix in rows and columns, wherein two antenna conductor loops adjacent in a row or in a column are inductively decoupled from one another; and wherein two antenna conductor loops diagonally adjacent to one another in adjacent rows and columns are capacitively decoupled from one another.
Claims13
An antenna arrangement for a magnetic resonance apparatus, comprising:
- at least four individually operable antenna conductor loops arranged in a matrix in rows and columns;
- two of said antenna conductor loops that are adjacent in a row or adjacent in a column being inductively decoupled from each other;
- and
- two of said antenna conductor loops that are diagonally adjacent in adjacent rows and adjacent columns being capacitively decoupled from each other.
A magnetic resonance apparatus comprising:
- a magnetic resonance data acquisition device configured to acquire magnetic resonance data from an examination subject therein, said magnetic resonance data acquisition device comprising a basic field magnet having an examination volume therein in which the patient is located, a gradient coil system that generates gradient fields in said examination volume, and an antenna arrangement for transmitting or receiving RF signals into and from said examination volume;
- and
- said antenna arrangement comprising at least four individually operable antenna conductor loops arranged in a matrix in rows and columns, two of said antenna conductor loops that are adjacent in a row or adjacent in a column being inductively decoupled from each other, and two of said antenna conductor loops that are diagonally adjacent in adjacent rows and adjacent columns being capacitively decoupled from each other.
A method for acquiring magnetic resonance signals with an antenna arrangement, comprising the steps of:
- forming an antenna arrangement by arranging four individually operable antenna conductor loops in a matrix in rows and columns;
- inductively decoupling two of said conductor loops from each other that are adjacent in a row or a adjacent in a column;
- and
- capacitively decoupling two of said antenna conductor loops from each other that are diagonally adjacent in adjacent rows and adjacent columns.
