Fiber optic systems for MRI suites and related devices and methods
First Claim
1. A surgical system for an MRI suite, comprising:
- an MRI compatible mouse residing in an MR Scanner room of the MRI suite, wherein the mouse is an optical mouse which emits a beam of light for detecting displacement of the mouse based on user movement of the mouse to thereby operate without a scroll wheel, wherein the mouse has a primary circuit board in a mouse housing, and wherein the mouse further comprises first and second EMI suppressors, one with a ground input connected to an EMI ground shield and one with a ground input connected to a shield of an RF shielded cable;
a fiber optic mouse interface in the MR Scanner room in communication with the mouse;
a length of the RF shielded cable attached to the mouse and extending between the mouse and the fiber optic mouse interface in the MR Scanner room, wherein the RF shielded cable provides a power input to the mouse and transmits and receives electrical signal in response to movement of the mouse; and
a fiber optic cable attached to the fiber optic mouse interface configured to connect a computer outside the MR Scanner room so that a user is able to move the mouse in the MR Scanner room to (i) move a cursor and (ii) select functions or actions in drop down menus presented by the computer to at least one monitor.

Abstract
Fiber optic systems with an MR compatible mouse in an MR scanner room that connects to a fiber optic computer mouse interface that is attached to a fiber optic cable that connects to a USB port of a computer in the MR control room to allow the mouse in the MR scanner room to move a cursor on a monitor in communication with the computer in the control room of an MRI suite during an MRI guided surgical procedure. The fiber optic cable(s) can be routed though a conventional RF wall waveguide and avoids the need for additional holes in the penetration panel for connectors. The fiber optic systems can also include up converters and down converters for providing fiber optic video signals from cameras in the MR scanner room to display video signal on the monitor.

14. A method of controlling an MRI guided surgery, comprising;
-
accepting user input from a mouse in an MR Scanner room of an MRI suite, wherein the mouse comprises first and second EMI suppressors, one with a ground input connected to an EMI ground shield and one with a ground input connected to a shield of an RF shielded cable; obtaining electrical signal associated with the user input using the RF shielded cable in the MR Scanner room that is attached to the mouse and that also powers the mouse; converting signal from the mouse to a fiber optic mouse signal in the MR Scanner room; transmitting the fiber optic mouse signal to a USB port on a computer outside the MR Scanner room via a first fiberoptic cable that is routed through a waveguide in an RF shielded wall between the MR Scanner room and an MR control room of the MRI suite; electronically moving a cursor and/or selecting actions or functions on a monitor with the computer using the transmitted fiber optic mouse signal; obtaining video signal from at least one camera in the MR Scanner room; up-converting the obtained video signal to a fiber optic signal in the MR Scanner room; transmitting the converted video signal via a second fiberoptic cable that is routed through the waveguide in the RF shielded wall; down-converting the video signal from the second fiberoptic cable outside the MR Scanner room; and displaying the down-converted signal on a display. - View Dependent Claims (15, 16)

17. A surgical system for an MRI suite, comprising:
-
an MRI compatible mouse residing in an MR Scanner room of the MRI suite, wherein the mouse comprises first and second EMI suppressors, one with a ground input connected to an EMI ground shield and one with a ground input connected to a shield of an RF shielded cable; a fiber optic mouse interface in the MR Scanner room in communication with the mouse; a first fiber optic cable attached to the fiber optic mouse interface connected to a computer in communication with at least one monitor outside the MR Scanner room so that a user is able to move the mouse in the MR Scanner room to (i) move a cursor and/or (ii) select functions or actions in drop down menus presented by the monitor outside the MR Scanner room; at least one camera attached to a camera cable in the MR Scanner room; and an up-converter device in the MR Scanner room attached to the camera cable and a second fiber optic cable spaced apart from the first fiber optic cable in the MR Scanner room and in communication with a down-converter device outside the MR Scanner room, wherein video to fiber optic signal from the second fiber optic cable is converted and transmitted by the up-converter to the down-converter which converts fiber optic signal to video. - View Dependent Claims (18, 19)
