The device’s image display is split into two views. The top includes a background bone enhanced ultrasound image with real‐time overlays indicating midline detection (red vertical dashed line), interlaminar space detection (orange overlay), and estimates of the spinous process depth (blue number) and epidural space depth (orange number). On the bottom of the device display screen is the 3D spine indicator. This model is useful in depicting device orientation relative to the spinal midline and interlaminar space. Once these landmarks are identified, a detachable, single-use LocatorTM needle guide is used to mark the needle insertion site.
