CONTRAST ENHANCEMENT FOR MEDICAL IMAGING

Abstract:

A method of visualizing tissue of a subject includes receiving a fluorescence image of the tissue of the subject, wherein the fluorescence image comprises a plurality of intensity values, a first portion of the intensity values are associated with a first fluorescence emission that is from fluorescence agent that is preferentially accumulated or activated in a target region in the tissue and a second portion of the intensity values are associated with a second fluorescence emission that is from fluorescence agent that is not located within the target region in the tissue; generating an enhanced fluorescence image by reducing one or more of the intensity values that are below a threshold intensity value to increase contrast between the target region in the tissue and areas that are associated with the fluorescence agent that is not located within the target region in the tissue; and displaying the enhanced fluorescence image.
