1. A method of displaying fluorescence intensity for imaged anatomy, the method comprising:
displaying images of the anatomy captured by an optical imaging device being aimed at the anatomy;
displaying a target reticle on the displayed images around a region of a field of view of the imaging device;
calculating a representation of normalized fluorescence intensity within the target reticle based on normalized fluorescence intensity values for a plurality of pixels within the target reticle;
displaying the representation of normalized fluorescence intensity in a display region associated with the target reticle;
moving the field of view of the imaging device and the target reticle relative to the imaged anatomy; and
updating the calculated and displayed representation of the normalized fluorescence intensity within the target reticle as the imaging device is aimed at different locations on the imaged anatomy.
