Abstract

Pointers are added to a 3D volumetric dataset to help the user visualize the direction of blood flow. A 3D volume containing at least one blood vessel is created. Next, the direction of the blood flow is determined. Next, at least pointer is placed into the 3D volume in an aligned fashion with the direction of blood flow such that the 3D volume is modified. Next, the modified 3D volume is displayed on a head display unit, such as an augmented reality or virtual reality display. Next, at least one pointer is advanced to a new position for additional modification of the 3D imaging volume.
