Magnetic resonance imaging color composites
First Claim
1. A method of analyzing a single color composite image produced from a plurality of multiparameter magnetic resonance images, the method including the steps of:
- identifying a region of interest in the composite image,identifying the proportional color contributions of red, green and blue of the selected region of interest;
analyzing the color coefficient values originally assigned to each independent image for the production of the color composite image and the average signal intensities of the regions of interest provided by each image;
listing potential anatomical, physiological or pathological features associated with the analyzed region of interest based on the proportional influence from each color contribution and image which produced the composite.

Abstract
The invention relates to an apparatus and method for producing a single color coded composite image from a plurality of multiparameter magnetic resonance image sets. The plurality of magnetic resonance image sets are spatially aligned and are acquired using different pulse sequences to contrast various parameters of anatomical, physiological and pathological features. The method includes acquiring the gray-tone images, and plotting a histogram of the average pixel signal intensities for selected regions of interest in each image. This provide quantitative data to support qualitative assessments of tissue contrast behavior in each of the images which acts as a basis for color coding. Based on the histogram, color coefficients of red, green and blue channels are assigned to each image so that the final combination of colors will produce a semi-natural appearing composite image. Monochrome images are created based on the gray-tone images and color coefficiency tables. The monochrome images are combined to produce the composite image.
