Abstract

A local coil for magnetic resonance applications includes a rigid housing that radially surrounds a substantially cylindrical examination volume. Arranged in the rigid housing is a transmitting coil, by which an excitation signal may be applied to the examination volume. An object to be examined arranged in the examination volume may be excited by the excitation signal for emitting a magnetic resonance signal. The local coil includes a size-variable structure, in which an antenna assembly for receiving the magnetic resonance signal emitted by the object to be examined is arranged. The size-variable structure is arranged in the examination volume and is connected to the rigid housing. The size-variable structure is soft and flexible.

Dependent claims

A receiving coil for magnetic resonance applications, the receiving coil comprising:

a soft, flexible enveloping structure, in which an antenna assembly for receiving a magnetic resonance signal is arranged, the enveloping structure being configurable so as to be flat, and extending over a length in a longitudinal direction and over a width in a width direction, the enveloping structure being bendable from the flat state into a ring that extends over the width in the direction of a ring axis,
wherein in the flat state, end regions of the enveloping structure that oppose each other with respect to the enveloping structure are joined together by a connecting structure in a state of the enveloping structure that is bent to form a ring, and
wherein, viewed in the width direction, at least one of the end regions is divided into lugs that, in the flat state, are individually connectable to one, when viewed in the longitudinal direction, opposing section of the other end region, so a respective ring circumference of the enveloping structure is individually adjustable for each of the lugs.
