ABSTRACT:
An optical system using a lens assembly with the screen of a computer CRT or LCD unit, said computer being coupled to an MRI apparatus for receiving data therefrom. Data from the MRI to be presented to the CRT screen is provided as a two-dimensional image rotatable about a selected axis. Light rays from the image pass through the slit of a curtain shutter so that a continuum of views of the image will be projected onto a lenticular film. In another embodiment a Ronchi grating is used. A film having an emulsion engages the back side of the Ronchi grating forwardly of a stationary lenticular screen. A motor drives the Ronchi grating transversely of the light rays. Thus, the rotating image will be represented by light rays which pass to the Ronchi grating. The light rays pass through the grating and expose the emulsion of the film. The film can then be processed and the continuum of images exposed on the film can be viewed through the lenticular screen as three-dimensional images of the two-dimensional image shown on the CRT screen and representing the MRI data. In the alternative, the Ronchi grating can remain stationary while the film moves relative to the grating.
