Abstract
Systems and methods for measuring short wave infrared fluorescence and autofluorescent signals are disclosed. In some embodiments, for example, a method may include exposing a portion of tissue that does not include a fluorescent probe to an excitation source of the tissue, wherein at least a portion of the tissue has an autofluorescence spectrum which includes wavelengths greater than 900 nm, and imaging the tissue with a detector that is sensitive to electromagnetic radiation with wavelengths greater than or equal to 900 nm. In certain other embodiments, a system comprises a fluorescent probe including a fluorescent component attached to a carrier, an excitation source, and a detector that detects a tail portion of the fluorescence of the fluorescent component. Methods associated with such a system are also disclosed.
