The invention provides methods of focusing an instrument for the acquisition of optical data from a tissue sample. Methods of the invention allow rapid focusing in the context of a diagnostic procedure in which rapid data acquisition is desirable. For example, inventive methods allow a user to focus an optical instrument quickly enough to obtain data within an optimal window of time following application of a chemical agent to the tissue. In one embodiment, a user focuses an optical instrument by aligning laser spots projected onto a tissue sample within rings that are superimposed at predetermined locations within the user's visual field. Preferred methods of the invention further comprise automatic validation to detect whether the spots are sufficiently well-aligned.

Methods and apparatus for evaluating image focus

The invention provides methods for displaying diagnostic results obtained from a tissue sample. In general, the invention assigns tissue-class probability values to discrete regions of a patient sample, and creates an overlay for displaying the results. The overlay facilitates display of the tissue class probabilities in a way that reflects the diagnostic relevance of the data. For example, methods of the invention comprise applying filtering and color-blending techniques in order to facilitate display of diagnostic results.
