How does a simulator assist radiation oncologists?

The simulator plays a critical role in radiation oncology by facilitating the localization of the Planning Target Volume (PTV) and Organs at Risk (OAR). This process involves accurately determining the exact locations of the tumor and surrounding healthy tissues before treatment planning begins.

Using a simulator, oncologists can visualize the tumor in relation to surrounding anatomy through imaging techniques like fluoroscopy or CT scans, which helps ensure that the radiation is precisely targeted to the intended area. This results in a more accurate treatment plan that maximizes radiation dose to the tumor while minimizing exposure to healthy tissues, thereby reducing potential side effects and improving patient outcomes.

The importance of this function cannot be overstated since successful radiation treatment relies heavily on the accurate identification of these critical areas. By effectively localizing both the PTV and OAR, the simulator enhances the overall quality and precision of radiation therapy.
