Final answer:
To adequately image a three-dimensional volume structure, three mutually perpendicular planes, including the base plane, and a 360o rotation are needed.
Step-by-step explanation:
To adequately image a three-dimensional volume structure, three mutually perpendicular planes are needed. By including three mutually perpendicular planes, it is possible to capture a comprehensive view of the volume from different angles. In addition, including the base plane helps to see the entire structure in its entirety. Doing a 360o rotation also aids in capturing the structure from all angles.
