Claim One:
1. An MRI system comprising: A magnet room; A magnet within the magnet room defining a patient receiving magnet bore; A control room associated with the magnet room; and an MRI forward predictive noise cancellation microphone system including: a. a microphone within the magnet room, the microphone adapted to receive both acoustic noise alone within the magnet room that forms a cancellation template and a combination of acoustic noise and patient speech within the magnet room, b. at least one receiving device outside the magnet room; and c. a controller receiving signals from the microphone and outputting an audio signal to the at least one receiver, (i) wherein the controller can operate in cancellation mode which subtracts the cancellation template from the signal received from the microphone, (ii) wherein the controller updates the cancellation template with a previous received signal that has been determined to be acoustic noise alone, and (iii) wherein the controller receives input from at least one of the technician, the patient and an MRI system controller that is indicative of patient speech occurring whereby the signal from the microphone will be considered acoustic noise and patient speech and will not be used to update the cancellation template, and wherein the system includes At least one of A) an MRI digital projection system for the MRI system including a. a source of video signal outside the magnet room, the source including a digital video interface; b. a digital video interface/fiber optic converter coupled to the video signal source; c. a fiber optic cable coupled to the digital video interface/fiber optic converter extending from the digital video interface/fiber optic converter into the magnet room; d. a fiber optic/digital interface converter within the magnet room and coupled to a distal end of the fiber optic cable; e. a digital light processing projector within the magnet room and coupled to the fiber optic/digital interface converter; f. a screen positioned within the magnet room and viewable by the patient within the magnet bore and configured to receive a viewable image from the digital light processing projector; and g. RF shielding within the magnet room extending around at least the fiber optic/digital interface converter and the digital light projector; or B) an MRI digital projection system for the MRI system including: a. a source of video signal outside the magnet room, the source including a digital video interface; b. a digital video interface/fiber optic converter coupled to the video signal source; c. a fiber optic cable coupled to the digital video interface/fiber optic converter extending from the digital video interface/fiber; d. a fiber optic/digital interface converter coupled to a distal end of the fiber optic cable; e. a digital light processing projector coupled to the fiber optic/digital interface converter, the projector including a RGB color wheel that spins at a determined frequency; f. a screen positioned within the magnet room and viewable by the patient within the magnet bore and configured to receive a viewable image from the digital light processing projector; and g. a synchronization unit for synchronizing the images on the screen, wherein the synchronization unit utilizes a control signal from the determined frequency of the color wheel; and wherein the Digital Light Processing Projector of the digital projection system of A) or B) utilizes a wave guide attached thereto to project the image onto the screen through one of a prism or mirror.
