Abstract

Apparatus and methods for magnetic resonance imaging are provided. The apparatus desirably comprises an MRI magnet subsystem and a control kiosk spatially separate from the MRI subsystem. The control kiosk may be advantageously located inside or outside the shielded room housing the MRI subsystem. The method comprises the steps of providing a control kiosk spatially separate from the MRI subsystem and positioning and viewing a patient within a patient-receiving space of the main subsystem. In accordance with another aspect of the invention, a magnetic resonance imaging apparatus comprising a relay having a power input and power output connected to a power supply of an actuator control unit is provided.

Claims

1. Apparatus for magnetic resonance imaging comprising:

an MRI magnet subsystem having a pair of pole faces;

a patient handling system capable of three of axes of motion between said pair of pole faces, wherein said three axes of motion includes a substantially horizontal direction, a substantially vertical direction, and a rotation of said patient handling system; and

a control kiosk spatially separate from said MRI subsystem and comprising a housing having first and second ends, said control kiosk being located in a room having a floor, the first end being supported by the floor and the second end having a control panel operable to control the motion of said patient handling system.

2. The apparatus of claim 1, further comprising one or more cables operationally connecting said control kiosk to said MRI magnet subsystem.

3. The apparatus of claim 2, wherein said one or more cables includes at least one data transmission cable or at least one data transmission cable and at least one power transmission cable.

4. The apparatus of claim 1, wherein said control kiosk is located such that an operator using said control kiosk can see said patient handling system.

5. The apparatus of claim 1, wherein said control kiosk is a touch-sensitive liquid crystal display.

6. A control kiosk spatially separate from a magnetic resonance imaging apparatus having a patient-receiving gap, said control kiosk comprising a support structure with a floor end, a floor collar and a top end and a control housing attached to said top end;

and, wherein said control housing includes a control panel mounting controls for operating a patient handling system positioned within the patient-receiving gap and capable of three axes of motion, wherein said three axes of motion of said patient handling system includes a substantially horizontal direction, a substantially vertical direction, and a rotation of said patient handling system,

and wherein said control housing can rotate with respect to said support structure.

7. The control kiosk of claim 6, wherein said floor collar attaches said floor end to the floor and wherein said control housing and said support structure rotate with respect to said floor collar.

8. The control kiosk of claim 6, wherein said support structure is a hollow tube.

9. The control kiosk of claim 6, wherein said support structure is made of a non-magnetic material.

10. The control kiosk of claim 9, wherein said support structure is made of aluminum.

11. The control kiosk of claim 6, wherein said controls mounted on said control panel include one or more elements selected from a group consisting of an on button and an off button, an emergency stop button, a home button for returning the patient handling system to a default position, and a movement button acting as a dead man'"'"'s switch.

12. An apparatus for magnetic resonance imaging comprising:

an MRI magnet subsystem having a first magnetic pole with a generally flat face and a second magnetic pole with a generally flat face;

said first and second magnetic poles defining a gap between said faces of said first and second magnetic poles, a generally horizontal pole axis running through the center of said faces of said first and second magnetic poles and a median line at the height of said pole axis which is generally equidistant at all points from the faces of the first and second magnetic poles, and a center point at the intersection of said pole axis and said median line;

a patient handling system capable of three axes of motion provided within said gap; and

a control kiosk spatially separate from said MRI magnet subsystem, said control kiosk usable by an operator to control said patient handling system,

wherein said control kiosk is located such that the operator has an unobstructed line of sight defined from the operator to the center point.

13. The apparatus of claim 12, further comprising a structural connection between said MRI subsystem and said control kiosk.

14. The apparatus of claim 13, wherein said structural connection is a load-bearing arm capable of holding said control kiosk off the floor.

15. The apparatus of claim 14, wherein said load-bearing arm further includes a pivot attaching said load-bearing arm to said MRI subsystem allowing said load-bearing arm to swivel about said pivot.

16. The apparatus of claim 15, wherein said control kiosk is a touch sensitive liquid crystal display.

17. The apparatus of claim 13, wherein said structural connection is a ceiling boom capable of holding said control kiosk above the floor.

18. The apparatus of claim 17, wherein said control kiosk is a touch-sensitive liquid crystal display.

19. The apparatus of claim 13, wherein said structural connection comprises a member mounted to floor for supporting said control kiosk.

20. The apparatus of claim 19, wherein said member further includes a pivot and said control kiosk further includes a control housing, said pivot allowing said control housing to swivel about said member.
