A method of obtaining information about a heterogeneous pharmaceutical mixture is disclosed. This method involves applying an image enhancement agent, such as a stain, to the mixture. An image of the mixture can then be obtained, and information about a distribution of components of the mixture in the image can also be obtained based on spatial information derived from the application of the image enhancement agent.La présente invention concerne un procédé permettant de recueillir de linformation sur un mélange pharmaceutique hétérogène. A cet effet, on applique au mélange un agent améliorant limage, tel quun colorant. Limage du mélange ainsi recueillie et linformation 3D dérivée de lapplication dudit agent permet de connaître la distribution des composants du mélange dans limage.
