Radiotherapy Department
Radiotherapy is a medical specialty that involves the use of sealed radioactive sources to irradiate cancerous and a few other non-malignant conditions. Ionizing radiation is effective in controlling a variety of malignant tumors by limiting tumor size as well as spread to other areas of the body.
The first step in radiotherapy is to accurately determine the size and extent of the tumor. This is done with the help of a simulator. The simulator is a fluoroscopic X-ray machine that simulates the conditions on the treatment machine. Accurate localization of tumor prevents the neighboring normal tissues from unwanted effects of radiations.
The second step is to prepare an accurate treatment plan. This is done by a medical physicist using treatment planning software.
