IMRT stands for Intense Modulated Radiation Therapy that uses linear accelerators to deliver
regulated amounts of radiation to the tumour cells. IMRT is a conformal therapy engineered to radiate beams to fit into the area of the cancer.
LINAC or linear accelerator is a standard radiotherapy machine used for the purpose. The equipment is inbuilt with a multileaf collimator containing thin
Planning the Treatment at Guru Hospitals
There are several steps to the IMRT treatment :
For the areas to be treated - a 360 deg. photo is taken with a CT scanner along with PET and MRI scans; dosage calculations are done along with a computer; the pattern of dissipation and strength of the dosage that synchronizes with the tumour shape is also assessed
Skin markings are made on the skin to clearly mark the areas of treatment.
For radiotherapy of the head and neck a plastic mould called a shell mask may be used to keep the treatment area still for greater accuracy of the treatment..
VMAT or volumetric modulated arc radiotherapy is one of the latest IMRT techniques. During treatment, the device rotates around the patient and simultaneously changes the intensity of the beams as it moves around.
IMRT can successfully treat breast cancer, cancers of the head and the neck.
IMRT is a precise, safe and painless treatment modality that can administer precise quantities of radiation to specific areas within the tumour or on the tumour itself. Consultants at Guru Hospitals will offer a comprehensive treatment plan and awareness about IMRT before administration of the treatment. Specific instructions are given to the patient undergoing IMRT.
