•
2D techniques
•
Planar images acquired
•
Detailed information about the depth of structures lost
•
3D co-ordinates of structures may be calculated however if two
images at two different angles are used.
•
3D techniques
2D vs. 3D
•
Volumetric information and require a sequence of images often
obtained using rotation of the source around the object.
•
Dose is greater than 2D
•
Ultrasound, kV and MV energy radiation may be used to
give 2D and 3D images.
