CT simulation transmits X-rays through tissue to create a graphic display of the tumor and surrounding normal tissue.
A CT Simulator allows for precise treatment planning by demonstrating the relationship between the target tumor and healthy tissues while the patient is in treatment position.
Using a high-speed, high-capacity computer, the CT simulator helps physicians understand the complex relationship between healthy and cancerous tissues. The information is recorded, analyzed and used to design an optimal treatment plan.
A 4-D CT differs from a standard static 3-D CT by showing tumor and normal tissue motion. The radiation oncologist and physicist tailor the radiation plan to account for movement of the target and normal tissues during treatment.
