ABSTRACT:
The invention relates to the determination and visualization of the spatial distribution of tissue states in histologic tissue sections on the basis of mass spectrometric signals acquired so as to be spatially resolved. The invention provides a method which determines the tissue state for the tissue spots as a state characteristic, which is calculated as a mathematical or logical expression from at least two mass signals of this tissue spot, and which indicates the tissue state as a gray-level or false-color image in one or two dimensions.
