Advanced Radiotherapy Eqipments uses the ionizing radiation (high-energy radiation that displaces electrons from atoms and molecules) to destroy cancer cells
These technologies have improved the quality of radiation treatment, by enabling precise positioning of the patients, and targeting of tumours minimising doses to normal healthy tissues.

The use of Radiotherapy Equipments in different treatments of cancer
Stereotactic Body Radiation Therapy (SBRT) is a radiation therapy approach which delivers high dose radiation to a target within the body, in either a single or up to five treatment sessions. It is similar to central nervous system stereotactic radiosurgery, except that it deals with tumors outside the central nervous system (CNS).
Higher therapeutic ratio
Minimally invasive and painless
alternative for patients who are unfit for surgeries
No Surgery, No Hospitalization
Minimized Side Effects
Excellent Long-Term Cancer Control
Intensity-modulated radiation therapy (IMRT) is an advanced mode of high-precision radiotherapy that uses computer-controlled linear accelerators to deliver precise radiation doses to a malignant tumor or specific areas within the tumor. IMRT allows for the radiation dose to conform more precisely to the three-dimensional (3-D) shape of the tumor by modulating—or controlling—the intensity of the radiation beam in multiple small volumes. IMRT also allows higher radiation doses to be focused on the tumor while minimizing the dose to surrounding normal critical structures.
In the beginning of the treatment session, the radiation therapist positions the patient on the treatment table, guided by the marks on the skin (tattoos) defining the treatment area. If molded devices were made, they will be used to help the patient maintain the proper position. The patient may be repositioned during the procedure. Imaging systems on the treatment machine such as x-ray or CT may be used to check positioning and marker location.
