The backbone of modern high precision radiotherapy is intensity modulation across all three dimensions. IMRT is a new paradigm shift in Radiation therapy which uses software based planning and delivery of tightly focused radiation beams to tumors with significantly reducing the radiation dose to surrounding healthy tissues and organs and there by reducing side effects.
Image Guided Radiotherapy - a step ahead of IMRT – delivers radiation with enhanced precision and accuracy towards precision. A CT scan of the patient is taken in treatment position everyday before delivering radiation using cone beam CT scanner attached to the linear accelerator which ensures the radiation is being delivered to the intended region in millimeter accuracy.
Stereotactic Radio surgery is a non surgical treatment modality involving high energy radiation to achieve results similar to surgery, especially in patients with small tumors in the brain. The patients are immobilized using rigid masks along with external markers and undergo CT scan and MRI to define the tumor. This procedure is carried out mainly for intracranial tumors
SBRT is a new procedure for treating small tumors of lung and liver cancer that uses high doses of radiation delivered to a precise target. By using special positioning and implanted markers in the body.
