Abstract
An imaging method and system generates images of non-planar portions of a three dimensional data point array wherein the non-planar portion corresponds to a non-planar object. The method includes selecting at least two different intermediate imaging planes, each selected plane including at least a portion of the object to be imaged, generating cross-sectional views perpendicular to each intermediate plane, selecting a viewing plane, projecting the cross-sectional views onto the viewing plane to generate transition value sets, and combining the transition value sets to generate values for each pixel in a display.

A system for displaying images of a three dimensional data array, the array including signal patterns representing the value of at least one physical property associated with a three dimensional body at regularly spaced grid locations defining volume elements within the body, the system comprising:
- a plane selector for arbitrarily choosing at least first and second intermediate planes through the body, the first and second intermediate planes including first and second sets of intermediate element positions, respectively;
- a determiner for determining the physical property value for each position of the first and second element position sets, thereby generating first and second intermediate element value sets, respectively;
- a viewing angle selector for selecting a viewing plane adjacent the intermediate planes, the viewing plane including viewing element positions;
- a processor for combining the intermediate element value sets to generate a value for each viewing element position;
- a two dimensional display for displaying an image;
- and
- a driver for receiving the viewing element positions and corresponding values and driving said display to produce an image on the display.
