Method for evaluating three-dimensional rendering systems
First Claim
1. A method for evaluating a three-dimensional rendering system employing a rendering engine having predetermined operating settings, the method comprising the steps of:
- (a) collecting three-dimensional image data;
(b) identifying a set of parameters affecting an image quality of two dimensional images produced by the rendering system;
(c) generating a set of two-dimensional images using the rendering system operating on the three-dimensional image data using different parameters of the set of parameters;
(d) producing for each two-dimensional image a mathematical index related to the image quality of the two-dimensional image; and
(e) fitting a functional relationship to the mathematical index and the parameters so as to allow rapid evaluation of the affect of a change in parameter on image quality;
(f) generating synthetic three-dimensional image data; and
wherein step (d) generates the mathematical index by comparing each two-dimensional image to an optimized two-dimensional image of the three-dimensional image data generated by using parameters obtained from evaluation of the synthetic three-dimensional image data.

Abstract
A method of automatically evaluating settings for three dimensional rendering engines establishes a mathematical equivalency to image quality such as may be RMS error. With this mathematical index, a gold standard setting may be established and used to compare clinical images with other settings. The image qualities for different settings may be fit to a functional model so as to provide rapid assessment of the affect on image quality of parameter adjustments. The time-cost for producing the image may also be fit to a surface to allow more complex time/image quality trade offs to be realized.
