Magnetic resonance system

摘要

A magnetic resonance system is disclosed, with a tunnel for accommodating an object under investigation and at least one local coil array. In at least one embodiment, the local coil array is arranged in a fixed position within the tunnel and in the longitudinal direction of the magnetic resonance system, where the geometry of the local coil array, in particular its diameter, can be altered. In at least one embodiment, for the purpose of arranging the local coil array on the patient's body, at least a proportion of the coils of the local coil array is attached to a fixture the volume of which can be altered, either hydraulically or pneumatically. The fixture is subdivided into chambers, the volumes of which can be altered separately in order to realize a bending of the fixture. Or, in at least one embodiment, for the purpose of arranging the local coil array on the patient's body at least a proportion of the coils of the local coil array is arranged on a lamellar structure so that they can be moved relative to each other.

主权项

1. A magnetic resonance system, comprising:
a tunnel for accommodating an object under investigation; and at least one local coil array arranged in a fixed location and in the longitudinal direction within the tunnel of the magnetic resonance system, a geometry of the local coil array being alterable, wherein for the purpose of arranging the local coil array on the object under investigation,
at least a portion of the coils of the local coil array is attached to a fixture, a volume of the fixture being alterable hydraulically or pneumatically, the fixture being subdivided into chambers, volumes of the chambers being separately alterable in order to realize a bending of the fixture, andat least a portion of the coils of the local coil array is arranged on segments of a lamellar structure so as to be movable relative to each other, wherein in a central region relative to the longitudinal axis of the tunnel, the local coil array is configured to attenuate less radiation than in edge regions of the tunnel for the purpose of adding at least one second imaging modality.
