1. A method of producing volume renderings from magnetic resonance image data in real time with user interactivity, the method comprising:
- collecting magnetic resonance image (MRI) from a magnetic resonance coil, the MRI data representative of shapes within an image volume;
transferring the MRI data to a computer; and
producing a three-dimensional rendering of a volume from the MRI data in real time with respect to the act of collecting MRI data from a magnetic resonance coil representative of shapes within the image volume by rendering a plurality of image slices;
wherein collecting MRI data, and transferring MRI data is performed continuously; and
displaying the three-dimensional volume rendering on a monitor at a rate of about 10 or more frames per second with a latency between the act of collecting MRI data and the act of displaying the three-dimensional volume rendering that is equal to or less than about one third of a second.
