A magnetic resonance imaging (MRI) imaging system. The system includes: at least one MRI device that images an object an image processor at least one photon detector of a first type to generate at least one first optical image of the object and at least one photon detector of a second type to generate at least one second optical image of the object. The image processor superimposes the MRI image, the first optical image(s) and the second optical image(s) so as to yield a rendered 3D computer MRI image of the object.
