Abstract

The present embodiments relate to an MR local coil arrangement and an MR unit. An MR local coil arrangement is disclosed including at least one MR antenna, an illumination unit with at least one light-generating unit to illuminate an illumination region, and a switching unit with at least one sensor to control the illumination unit.

First claim

The invention claimed is:

1. A magnetic resonance (MR) local coil arrangement comprising:
at least one MR antenna;
an illumination unit with at least one light-generating unit configured to illuminate an illumination region of a patient; and
a switching unit with at least one sensor configured to control the illumination unit, the at least one sensor comprising at least one proximity sensor, at least one motion sensor, or the at least one proximity sensor and the at least one motion sensor,
wherein the switching unit is configured to switch the illumination unit between at least two operational states without an operator touching the switching unit.

2. The MR local coil arrangement of claim 1 , wherein the illumination unit is configured to illuminate the illumination region of the patient with light that differs in the at least two operational states with regard to an intensity of the light, a color of the light, or the intensity of the light and the color of the light.

3. The MR local coil arrangement of claim 1 , wherein the at least one proximity sensor, the at least one motion sensor, or the at least one proximity sensor and the at least one motion sensor comprises at least one optical sensor, at least one acoustic sensor, at least one capacitive sensor, or a combination thereof.

4. The MR local coil arrangement of claim 1 , wherein the switching unit is configured to be operated via gesture control.

5. The MR local coil arrangement of claim 1 , wherein the at least one light-generating unit is configured to beam light directly into the illumination region of the patient.

6. The MR local coil arrangement of claim 1 , wherein the at least one light-generating unit comprises at least one light-emitting diode.

7. The MR local coil arrangement of claim 1 , wherein the illumination unit comprises at least two partial illumination units arranged on opposite sides of the MR local coil arrangement.

8. The MR local coil arrangement of claim 7 , wherein the switching unit comprises a partial switching unit for each partial illumination unit of the at least two partial illumination units.

9. The MR local coil arrangement of claim 1 , wherein the MR local coil arrangement comprises a biopsy unit arranged at least partly inside the illumination region of the patient.

10. The MR local coil arrangement of claim 1 , further comprising:
a housing having a region recessed inwards,
wherein the at least one light-generating unit is arranged in the region recessed inwards.

11. A magnetic resonance (MR) device comprising:
at least one MR local coil arrangement comprising:
at least one MR antenna;
an illumination unit with at least one light-generating unit configured to illuminate an illumination region of a patient; and
a switching unit with at least one sensor configured to control the illumination unit, the at least one sensor comprising at least one proximity sensor, at least one motion sensor, or the at least one proximity sensor and the at least one motion sensor,

wherein the switching unit is configured to switch the illumination unit between at least two operational states without an operator touching the switching unit.

12. The MR device of claim 11 , further comprising:
a patient couch having a positioning plane,
wherein the at least one light-generating unit is configured to transmit a beam of light in a direction of the positioning plane of the patient couch.
