Abstract
The present disclosure provides a system for interrogating tissue comprising a light source for illuminating tissue comprising lesions from ablation and a sensor being configured to receive light to detect autofluorescence from the illuminated tissue. The sensor detects light at a first wavelength in a first wavelength range such that the first wavelength range includes a peak intensity of autofluorescence from the illuminated tissue and detecting light at a second wavelength in a second wavelength range such that the second wavelength range is 20 nm-100 nm longer than the first wavelength range. A processor is programmed to generate a first digital representation of the tissue from light detected in the first wavelength range and a second digital representation of the tissue from light detected in the second wavelength range, and generate a final digital representation from the first and second digital representations. The final digital representation distinguishes between ablated and non-ablated tissue.
