Ultrasound slice enhancement

In one embodiment a system includes a ultrasound probe to capture 2D ultrasonic images of a body part of a living subject, a process to generate a 3D anatomical map of the body part, the 3D anatomical map and the 2D ultrasonic images being registered with a 3D coordinate space, add a 3D indication of an anatomical structure to the 3D anatomical map, render to a display the 3D anatomical map including the 3D indication of the anatomical structure, and render to the display a given one of the 2D ultrasonic images with a 2D indication of the anatomical structure on the given 2D ultrasonic image responsively to the 3D indication of the anatomical structure.
