Abstract

Systems and methods for operating a magnetic resonance imaging (MRI) system are provided. The MRI system includes a magnetics system and a power system configured to provide power to at least some of the magnetics system. The power system includes an energy storage device and a power supply configured to receive mains electricity. The MRI system also includes at least one controller configured to control the MRI system to operate in accordance with a pulse sequence at least in part by generating, by using power supplied by the power supply and supplemental power supplied by the energy storage device, at least one gradient field using at least one gradient coil of the magnetics system.

First claim

What is claimed is:

an energy storage device; and
a power supply configured to receive mains electricity; and

a conveyance mechanism allowing the MRI system to be transported to different locations;
wherein the energy storage device and the power supply are disposed on-board the MRI system such that the conveyance mechanism transports the energy storage device and the power supply with the MRI system; and
wherein a power consumption of the MRI system is 4000 W or less.

2. The MRI system of claim 1 , wherein the power consumption of 4000 W or less is a peak power consumption.

3. The MRI system of claim 2 , wherein an average power consumption of the MRI system is 1500 W or less.

4. The MRI system of claim 1 , wherein the power consumption of the MRI system is 3000 W or less.

5. The MRI system of claim 4 , wherein the power consumption of 3000 W or less is a peak power consumption.

6. The MRI system of claim 1 , wherein the power consumption of the MRI system is 2000 W or less.

7. The MRI system of claim 6 , wherein the power consumption of 2000 W or less is a peak power consumption.

8. The MRI system of claim 1 , wherein the power consumption of the MRI system is 1500 W or less.

9. The MRI system of claim 8 , wherein the power consumption of 1500 W or less is an average power consumption.

10. The MRI system of claim 1 , wherein the conveyance mechanism comprises a motorized component configured to receive power from the power system to facilitate transportation of the MRI system to different locations.

11. The MRI system of claim 10 , wherein the motorized component comprises a motorized wheel.

12. The MRI system of claim 1 , wherein the energy storage device is coupled to the MRI system using a bidirectional DC-to-DC power converter, and wherein the bidirectional DC-to-DC power converter comprises a synchronous buck DC-to-DC power converter, a synchronous boost DC-to-DC power converter, or a four switch buck-boost DC-to-DC power converter.

13. The MRI system of claim 1 , wherein the power supply is further configured to provide power to the energy storage device and the MRI system concurrently.

14. The MRI system of claim 1 , wherein the energy storage device comprises a battery.

15. The MRI system of claim 1 , wherein the power supply is configured to provide power and the energy storage device is configured to provide supplemental power to the MRI system at least once per period of a pulse sequence.

16. The MRI system of claim 1 , wherein the energy storage device and the power supply are configured to provide a peak power that is greater than or equal to 1500 W and less than or equal to 4000 W.

17. The MRI system of claim 1 , wherein the energy storage device and the power supply are configured to provide a peak power for a length of time that is greater than or equal to 1 ms and less than or equal to 200 ms.

18. The MRI system of claim 1 , further comprising:
a transfer switch configured to couple the energy storage device to a motorized component of the conveyance mechanism or to a magnetics system of the MRI system.

19. The MRI system of claim 1 , further comprising:
