1. A magnetic resonance imaging system comprising:
a magnetic resonance imaging gantry having an inner bore;
a table translatable relative to the magnetic resonance imaging gantry;
a projector;
a projection screen, wherein the projection screen is positioned, relative to the projector, to provide a display surface for images projected by the projector; and
a mirror supported relative to the projection screen such that the images projected onto the projection screen are viewable through the mirror by a patient when the patient is residing on the table;
wherein the projector, the mirror and the projection screen are supported relative to the table such that they move in unison with the table while maintaining a fixed spatial relationship therebetween, and such that images projected by the projector onto the projection screen during translation of the table are projected with a constant projected image field size, thereby reducing a perception of motion by the patient as the patient is translated relative to the magnetic resonance imaging gantry
wherein the mirror, the projector and the projection screen are positionable within the bore of the magnetic resonance imaging gantry such that (i) the mirror resides within a body coil imaging region of the magnetic resonance imaging gantry and (ii) the projector resides outside the body coil imaging region without extending beyond an end of the magnetic resonance imaging gantry.
