A display method is proposed in which the relaxation times T1 and T2, and the proton density of tissue in each pixel in an MR image are simultaneously expressed in color features in a unified way. MR images were made from phantoms, volunteers and patients in such a way that T1 and T2 and proton density images could be calculated. Color images were computed from these images using matrix multiplication on a pixel base. In this way the color combination in each pixel represents the properties of that particular pixel by a unique mixing of the elementary colors red, green and blue. Color resolution could be modified using different choices of a reference color triangle in which the color combinations were defined. This method of representation offers a means for displaying multiple features as T1 and T2 in one directly interpretable image, independent of instrumental settings.
