CT Simulator is a tool used in the computed tomography (CT) simulation process for planning radiation therapy. This facility consists of a CT scanner equipped with additional devices to assist in the accurate determination of tumor size, location, and shape before radiation therapy begins.

Following are some of the main features of CT Simulator:

• Large-bore CT scanner: allows scanning of patients of various sizes.
• Flat table: mimics the patient's position during radiation therapy.
• Laser device: helps in marking the patient's position for radiation therapy.
• Virtual simulation software: enables more accurate treatment planning.

This CT simulation process is very important to ensure that radiation therapy can be carried out correctly, minimizing damage to healthy tissue around the tumor.
