Nerve Contour Tracking for Ultrasound-Guided Regional Anesthesia

摘要

Ultrasound-Guided Regional Anesthesia is a technique to provide regional anesthesia aided by ultrasound visualization of the region on which the anesthesia will be applied. A proper detection and tracking of the nerve contour is necessary to decide where anesthesia should be applied. If the needle is too far from the nerve contour, the anesthesia could be ineffective, but if it touch the nerve could harm the patient. In this paper we address a model to track nerve contours in ultrasonic videos to assist the doctors during Ultrasound-Guided Regional Anesthesia procedures. The experimental results show that our model performs good within an acceptable margin of error.
