Abstract

A patient couch for use in a medical imaging system that includes a gantry, a power supply unit and a driving unit for positioning the patient couch with respect to the gantry. The patient couch includes at least a first connector for supplying a wireless coil (e.g., a radio frequency (RF) coil for an MRI imaging apparatus) with power. The patient couch is detachably connected to the gantry. The power supply is configured to supply the first connector with power and an optional clock synchronization signal.

First claim

The invention claimed is:

1. A medical imaging apparatus, comprising:
a gantry including a power supply unit and circuitry;
a couch having a plurality of connectors to respectively supply, via a corresponding plurality of cables, a plurality of wireless coils with power from the power supply unit so that the plurality of coils are conductively connected to the power supply unit during a scan performed by the medical imaging apparatus, wherein during the scan, each of the plurality of wireless coils transmits data wirelessly to the circuitry such that none of the plurality of connectors receives data from the plurality of wireless coils, and no other connectors are provided on the couch for a wired data connection to the plurality of wireless coils; and
a driving unit configured to position the couch with respect to the gantry.

2. The medical imaging apparatus according to claim 1 , wherein the couch further comprises a first connector for connecting to a second connector, the second connector being on the gantry,
wherein the power supply unit supplies power to the couch via the first and second connectors.

3. The medical imaging apparatus according to claim 1 , wherein the couch is configured to be detachably connected to the gantry.

4. The medical imaging apparatus according to claim 1 , wherein the plurality of connectors respectively supplies the plurality of wireless coils with DC power.

5. The medical imaging apparatus according to claim 1 , wherein the plurality of connectors respectively supplies the plurality of wireless coils with DC power and a clock signal.

6. The medical imaging apparatus according to claim 1 , wherein the plurality of connectors respectively supplies the plurality of wireless coils with AC power.

7. The medical imaging apparatus according to claim 1 , wherein each of the plurality of connectors j integrated into a sliding receptacle.

8. The medical imaging apparatus according to claim 1 , wherein a first connector of the plurality of connectors is integrated into a first sliding receptacle and a second of the plurality of connectors is integrated into a second sliding receptacle independently slidable from the first sliding receptacle.

9. The medical imaging apparatus according to claim 1 , wherein the plurality of cables comprises a plurality of coaxial cables.

10. The medical imaging apparatus according to claim 1 , wherein the plurality of cables is permanently affixed to the plurality of wireless coils.

11. The medical imaging apparatus according to claim 1 , wherein the plurality of connectors is connected to the couch adjacent to where a patient is configured to lie while being imaged.

12. A medical imaging apparatus, comprising:
a power supply unit;
a gantry;
a couch having a plurality of connectors to respectively supply, via a corresponding plurality of cables, a plurality of wireless coils with power from the power supply unit, wherein the plurality of connectors do not receive data from the plurality of wireless coils; and
a driving unit configured to position the couch with respect to the gantry,
wherein the plurality of cables comprises a plurality of triaxial cables.

13. A medical imaging apparatus, comprising:
a power supply unit;
a gantry;
a couch having a plurality of connectors to respectively supply, via a corresponding plurality of cables, a plurality of wireless coils with power from the power supply unit, wherein the plurality of connectors do not receive data from the plurality of wireless coils; and
a driving unit configured to position the couch with respect to the gantry,
wherein the plurality of cables comprises a plurality of shielded twisted pair cables.

14. A medical imaging apparatus, comprising:
a power supply unit;
a gantry;
a couch having a plurality of connectors for respectively supplying a plurality of wireless coils with power from the power supply unit, wherein the plurality of connectors do not receive data from the plurality of wireless coils;
a driving unit configured to position the couch with respect to the gantry; and
at least one additional connector connected to the couch underneath where a patient is configured to lie while being imaged.
