Abstract
A magnetic resonance tomography unit includes a control unit, a transmitting unit having one or a plurality of transmitting antennae, a selector, and a high-frequency unit having a signal output in signal connection with the transmitting unit. The transmitting unit is configured to irradiate high-frequency energy using the selector and the one or plurality of transmitting antennae optionally into only a first region of a plurality of different regions in a patient.
Claims12
A magnetic resonance tomography unit comprising:
- a controller;
- a transmitter comprising one or more transmitting antennae;
- a selector;
- and
- a high-frequency unit having a signal output in signal connection with the transmitter,
- wherein the magnetic resonance tomography unit is configured to irradiate high-frequency energy into a patient using the selector and the one or more transmitting antennae.
A method for operating a magnetic resonance tomography unit, wherein the magnetic resonance tomography unit comprises a controller, a transmitter, a selector, and a high-frequency unit having a signal output in signal connection with the transmitter, the transmitter having one or more transmitting antenna, the method comprising:
- detecting, by the controller using a position detector, a position of a patient relative to the transmitter;
- detecting, by the controller, a region to be examined;
- determining and implementing, by the controller, a setting of the selector that is required for excitation of spins in the region to be examined by the one or more transmitting antennae;
- and
- emitting, by the high-frequency unit and the transmitter, a high-frequency pulse for excitation of the spins in the region to be examined.
A non-transitory computer-readable storage medium storing instructions executable by a controller of a magnetic resonance tomography unit to operate the magnetic resonance tomography unit, wherein the magnetic resonance tomography unit comprises a controller, a transmitter, a selector, and a high-frequency unit having a signal output in signal connection with the transmitter, the transmitter having one or more transmitting antenna, the instructions comprising:
- detecting, by the controller using a position detector, a position of a patient relative to the transmitter;
- detecting, by the controller, a region to be examined;
- determining and implementing, by the controller, a setting of the selector that is required for excitation of spins in the region to be examined by the one or more transmitting antennae;
- and
- emitting, by the high-frequency unit and the transmitter, a high-frequency pulse for excitation of the spins in the region to be examined.
