Local coil for a magnetic resonance imaging system and magnetic resonance imaging system
First Claim
1. A local coil for a magnetic resonance imaging system for acquisition of magnetic resonance signals, the local coil comprising:
- an antenna configured, due to an electric potential difference of a supply field present in a region of the local coil, to generate a current flow; and
a receiving mechanism for wireless transmission of operating energy of the local coil or the operating energy and a signal of the magnetic resonance imaging system,wherein the receiving mechanism is operable to take the operating energy or the operating energy and the signal of the magnetic resonance imaging system from the supply field configured as an electrical alternating field between a field source and a field sink, andwherein the receiving mechanism is configured such that the operating energy of the local coil or the operating energy and the signal of the magnetic resonance imaging system is taken from the current flow.

Abstract
A local coil for a magnetic resonance imaging system for acquisition of magnetic resonance signals includes a receiving mechanism for wireless transmission of operating energy of the local coil and/or a signal of the magnetic resonance imaging system. The receiving mechanism is configured to take the operating energy and/or the signal from a supply field. A magnetic resonance imaging system is also provided. The magnetic resonance imaging system includes a transmitting mechanism for wireless transmission of operating energy of a local coil and/or a signal of the magnetic resonance imaging system. The transmitting mechanism has a transmission signal generator that is connected to a field source and a field sink. The transmitting mechanism is constructed such that, in operation, the operating energy and/or the signal is transmitted by a supply field that is present as an electrical alternating voltage field between the field source and the field sink.
