Abstract
Abstract A technique for integrating voxelly-assigned information regarding a portion of anatomy derived from a number of sources into an accurate, single two dimensional pixel-based representation of a view of that anatomy is disclosed. Empirical relationships between known properties are used to infer values for unknown properties.

Claim 1
Independent Claim
240 words
A method for determining a measurement of a physical property of interest associated with the discrete spatial locations of a three dimensional object, wherein each spatial location of the three dimensional object has a unique address, and wherein the three dimensional object is composed of a plurality of types of matter, each type of matter having at least two properties, comprising the steps of: generating a first set of data reflective of at least a first physical property accessible by a first imaging technique and scanner for each spatial location of the area of interest; generating a second set of data reflective of at least a second physical property accessible by a second, different imaging technique and scanner for each spatial location of the area of interest; storing the data generated by the first and second imaging techniques in a memory storage device along with the address of each spatial location; and assigning to each unique address a first value, said first value representing the measurement of said property of interest for each unique address, said first value based on a correlation between said property of interest with the measure of the first physical property obtained in the first imaging scan taken and the correlation between said property of interest with the measure of the second physical property obtained in the second imaging scan taken, such that said property of interest is different from said first and second physical properties.
