4 D Computed Tomography Planning and Delivery
Conventional Computed Tomography (CT) uses x-rays to produce a 3D image of the patient. In a similar fashion, 4-D CT can produce a movie loop according to patient’s breathing pattern. Since CTs are 3D, if we add time as a 4th dimension, we have a “4D CT” or a 3D movie loop showing the motion of your internal organs as the patient breathes. We can use this to help us track and treat more effectively.

By tracking breathing patterns, this system applies the radiation beam only when the tumor falls within the planned treatment field. Patient breathes naturally and remains comfortable throughout the entire procedure.
