Abstract

An electrocardiography device (ECG device) designed for use in combination with a magnetic resonance device, including: a carrier unit; a receiving unit designed to mount on the carrier unit; an electrode; an electrode conductor connecting the electrode to the receiving unit, wherein the electrode conductor is stabilized at least partially by way of a shapeable guide element.

First claim

The invention claimed is:

1. An electrocardiography (ECG) device designed for use in combination with a magnetic resonance device, comprising:
a carrier unit designed to mount on a patient table;
a receiving unit designed to mount on the carrier unit such that during an examination the receiving unit is above an examination object at a defined spacing from the patient table;
an electrode; and
an electrode conductor connecting the electrode to the receiving unit,
wherein the electrode conductor is stabilized at least partially by way of a shapeable guide element.

2. The electrocardiography (ECG) device as claimed in claim 1 , wherein the shapeable guide element comprises a stabilizing component selected from a group of components consisting of:
MR-insensitive metal wire; aluminum wire; and copper wire and flexibly mutually engaging and connected hemispheres and/or spheres.

3. The electrocardiography (ECG) device as claimed in claim 1 , wherein the shapeable guide element has a length of between 5 cm and 25 cm.

4. The electrocardiography (ECG) device as claimed in claim 1 , wherein a length of the shapeable guide element corresponds to at least 80% of the length of the electrode conductor.

5. The electrocardiography (ECG) device as claimed in claim 1 , wherein starting from an end of the electrode conductor adjoining the electrode, between 0.3 cm and 3 cm of the electrode conductor is free of a stabilization by the shapeable guide element.

6. The electrocardiography (ECG) device as claimed in claim 1 , wherein the carrier unit comprises a fixing unit designed to accommodate the receiving unit.

7. The electrocardiography (ECG) device as claimed in claim 1 , wherein the carrier unit comprises a manually stiffly shapeable carrier structure.

8. The electrocardiography (ECG) device as claimed in claim 1 , wherein the carrier unit comprises a stable frame to position above a ribcage of the examination object.

9. The electrocardiography (ECG) device as claimed in claim 1 , comprising:
a movement sensor unit arranged on the electrode conductor and/or the shapeable guide element, designed to capture a movement of the electrode conductor.

10. The electrocardiography (ECG) device as claimed in claim 9 , wherein the movement sensor unit comprises a movement detection unit and a first electrical conductor, and the movement detection unit is designed to capture the movement of the electrode conductor based on a continuous measurement of an electrical resistance in the first electrical conductor.

11. A magnetic resonance (MR) device, comprising:
a detector unit designed to record an MR signal of the examination object which is arranged within a patient receiving region which is at least partially surrounded by the detector unit; and
an electrocardiography (ECG) device as claimed in claim 1 , the ECG device being arranged within the patient receiving region and being designed to capture an ECG signal from the examination object.
