Abstract: Disclosed is a liquid cooling system for use with MRI positioned video projectors to dissipate heat from the projector light source through liquid cooling. The system includes a heat sink body for mounting to the projector light source, the heat sink body constructed of a material to transfer heat away from the projector light. A remotely mounted motor-driven pump provides fluid circulation, the pump is constructed and/or mounted so as to not to be effected by the MRI magnetic field. The pump is coupled to the heat sink block by use of flexible tubing that is constructed and arranged to provide heat transfer to the environment thereby maintaining the projector light source temperature at a reduced level. A liquid reservoir is fluidly coupled to the pump intake for use in maintaining liquid levels at an optimum position.

Abstract: The MRI video system is a display system that provides visual stimuli to a patient who is undergoing diagnostic treatment within a magnetic resonance imagery (MRI) apparatus. The system utilizes a magnetically inert and RF shielded projector located in the close proximity to the MRI to transpose a video picture on a translucent screen inside the bore of the MRI. The patient views the screen through a prism.
