Abstract

A subject support ( 22 ) of a magnetic resonance (MR) system ( 10 ) includes a table top ( 20 ) supported by a support structure ( 24 ) and configured to move in and out of an examination volume ( 14 ). The subject support ( 22 ) further includes a coil connector ( 34 ) connected with a local receive coil ( 32 ). The coil connector ( 34 ) moves between an engaged position in which the coil connector ( 34 ) and the local receive coil ( 32 ) engage and move with the table top ( 20 ) in and out of the examination volume ( 14 ) and a disengaged position in which the coil connector ( 34 ) and the local receive coil ( 32 ) remain stationary out of the examination volume ( 14 ) as the table top ( 20 ) moves in and out of the examination volume ( 14 ).

First claim

Having thus described the preferred embodiments, the invention is now claimed to be:

1. A subject support for a magnetic resonance (MR) system comprising:
a table top supported by a support structure and configured to move in and out of an examination volume; and,
a coil connector connected with a local receive coil, the coil connector moving between an engaged position in which the coil connector and the local receive coil engage and move with the table top in and out of the examination volume and a disengaged position in which the coil connector and the local receive coil remain stationary out of the examination volume as the table top moves in and out of the examination volume.

2. The subject support according to claim 1 , further including:
one or more travel guides along which the table top travels in and out of the examination volume; and,
an independent travel guide along which the coil connector travels when in the engaged position.

3. The subject support according to claim 1 , wherein the coil connector mechanically and electrically connects with the table top only in the engaged position.

4. The subject support according to claim 1 , wherein the coil connector rotates between a horizontal position and a vertical position, the horizontal position disengaging the coil connector and the vertical position engaging the coil connector.

5. The subject support according to claim 1 , wherein an arm of the coil connector mates with a corresponding notch in the table top when the coil connector is in the engaged position.

6. The subject support according to claim 1 , wherein an electrical and/or optical connector of the coil connector mates with a corresponding electrical and/or optical connector of the table top when the coil connector is in the engaged position.

7. The subject support according to claim 1 , further including:
a storage pouch which stores the local receive coil when the coil connector is in the disengaged position.

8. The subject support according to claim 1 , wherein the receive coil is permanently connected to the subject support.

9. A magnetic resonance (MR) system comprising:
the subject support according to claim 1 ; and,
an MR scanner defining the examination volume.

10. A method for MR data acquisition using the subject support according to claim 1 , said method comprising:
positioning a subject on the table top;
positioning the local receive coil on and/or over the subject;
moving the coil connector to the engaged position;
moving the table top, the coil connector, and the local receive coil into the examination volume; and,
acquiring MR data from the local receive coil.

11. The method according to claim 10 , further including: removing the local receive coil from a storage pouch mounted to the side of the support structure prior to positioning the local receive coil on and/or over the subject.

12. The method according to claim 10 , wherein the engaging includes:
rotating the coil connector from a generally horizontal position to a generally vertical position to cause the coil connector to engage the table top to move therewith.

13. The method according to claim 10 , wherein the engaging includes:
establishing an electrical and/or optical connection path between the coil connector and the table top.

14. The method according to claim 10 , wherein the engaging includes:
mechanically connecting the coil connector to the table top.

15. The method according to claim 10 , wherein the moving includes:
sliding and/or rolling the table top and the coil connector into and out of the examination volume along travel guides of the support structure.
