APPROACH TO EXAMINATION
The electromagnetic eTRAX needle tip can be visualized in precise position as it enters the skin as well as its projected path for advancement to target. The on-screen guideline reveals the direction of travel with “N” representing the actual needle tip. Actual needle tip tracking was useful for accurate visualization throughout the puncture.
