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.
How is CT Simulation Used?
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.
How is 4-D CT Different from 3-D CT?
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.
