Abstract: A method of sampling a target tissue in an animal body, comprising the steps of inserting a endoscope-needle system into the animal body, guiding the endoscope-needle system along a path toward the target tissue using a Doppler-based optical coherence tomography (OCT) system coupled with machine-learning-based computer-aided diagnosis (ML-CAD), wherein the Doppler-based OCT system coupled with ML-CAD enables the identification of blood vessels along the path in advance of the needle tip of the endoscope-needle system thereby substantially avoiding damage to the blood vessels along the path as the needle tip of the endoscope-needle system is guided into the target tissue, after the needle tip is guided into the target tissue, and removing a tissue sample from the target tissue.
