Respiratory Gating 4-Dimensional CT

Accurate delineation of a disease site is crucial to the precise planning and delivery of radiation therapy. However, the body does not always remain still during treatment, and for precise treatment of tumors of the lung or abdomen, even normal respiration can present a challenge. The 4-dimensional CT scanner with respiratory gating technology allows us to address tumor motion in such circumstances. Gating gives us the ability to effectively compensate for tumor motion by operating the radiation beam only when the tumor is in the desired location within the field of view.
