CA3080998A1 — Methods and systems for spatially identifying abnormal cells

USPTO Abstract

A method for identifying abnormal cells compares healthy tissue fluorescence intensity with abnormal tissue fluorescence intensity to determine a threshold fluorescence intensity to discriminate between abnormal tissue and healthy tissue of a patient. At least one of a healthy tissue signal and abnormal tissue signal are used to determine the desired threshold. A tumor bed is illuminated with an excitation light. Fluorescence signals are detected from the tumor bed and the intensity of the fluorescence signal of the tumor bed is compared to the threshold fluorescence intensity to identify abnormal cells.
