Method And System For Determining An Optimal Insertion Segment In A Blood Vessel Of A Patient

Abstract: Method for determining at least one optimal insertion segment (810a, 810b, 810c, 810d) in a patient's limb, for the purposes of inserting a needle into a vein of the patient, the segment (810a, 810b, 810c, 810d) being representative of an insertion point (820a, 820b, 820c, 820d), an insertion direction and a maximum insertion length, the method comprising a step of illuminating, by means of near infrared illumination, the patient's limb, a step of acquiring near infrared images of the patient's limb, a step of pre-processing the acquired images to obtain an image of the veins, a step of applying a linear structure detection filter to the image of the veins to obtain a vascular profile map, a step of binarising the vascular profile map, a step of skeletonising the veins, a step of defining insertion segments on the basis of the skeletonised veins, and a step of classifying the insertion segments according to predetermined classification parameters.
