3 DIMENSIONAL RADIOTHERAPY(3DCRT) – Best Radiation Oncologist in India
3DCRT is the most simple form of radiotherapy. Tumors take different shapes and sizes, and are never in regular form. In 3dcrt , we use MLC ( multileaf collimator ) to precisely shape the tumor and avoid spillage of radiation to other normal structures. MLC`s are device with a computer controlled leaf like structure mainly used to shape the tumor. 3DCRT can be combined ABC for all
INDICATED IN – Breast cancer, Sarcomas, Lymphomas, Glottic Cancers
INTENSITY MODULATED RADIOTHERAPY (IMRT)
IMRT is a more advanced radiation technique.MLC used in 3dcrt is further divided into many small beams , which are directed towards the tumor from various directions and they give more conformable shape to the tumor, which helps in precise targeting , with no dose to surrounding normal structures. It is used in tumors like head and neck, stomach, oesophagus, gynecological cancers .
INDICATED IN – Head and neck cancers, Cervical cancers, Lung cancers, Uterine cancers
VMAT – Volumetric Modulated arc therapy
VMAT is a special form IMRT , VMAT can also be called Rapid Arc. VMAT is different to normal IMRT in that the radiotherapy machine rotates around the patient during a radiotherapy beam in an arc shape. The machine continuously reshapes and changes the intensity of the radiation beam as it moves around the body.
INDICATED IN – Head and neck cancers and Prostate cancers
BRACHYTHERAPY
Brachytherapy is a form of internal radiation , where in radioactive isotope,(Iridium 192) is put very close to tumor, as result very high dose is given to tumor with very minimal complications to normal tissues . It is mainly used in gynecological cancers , and its done under general anesthesia and patient goes back home same the day .
INDICATED IN – Cancer cervix, cancer Uterine , Ca Oesophagus
2D COMPLEX RADIOTHERAPY
This is a simple conventional treatment done with our linear accelerator. Earlier conventional treatments were done in Cobalt machines , now all conventional treatments are like a 3dcrt with CT based planning and portal imaging for more accuracy.
INDICATED IN – Multiple Bone metastases for pain relief
INTENSITY MODULATED RADIOTHERAPY
IMRT is a more advanced radiation technique.MLC used in 3dcrt is further divided into many small beams , which are directed towards the tumor from various directions and they give more conformal shape to the tumor, which helps in precise targeting , with no dose to surrounding normal structures. It is used in tumors like head and neck, stomach, oesophagus, gynecological cancers
SRS/SRT – STEREOTACTIC RADIOTHERAPY
Radiosurgery is an alternative to traditional neurosurgery , basically a bloodless surgery done on a day care basis , where patent goes home the same day after the treatment. All the complications pertaining to surgery can be avoided with this technique , and infact better results than surgery is possible .With our APEX MLC, we can get better conformity and treat tumors which are upto 1cms with excellent accuracy. With the addition of HEXApod couch( robotic couch) to this treatment , we can get sub millimeter accuracy so our targeting is more accurate .
SBRT – STEREOTACTIC BODY RADIOTHERAPY
SBRT is an latest technique of radiation , where in very high dose of radiation is given to small tumors to achieve good local control. Tumors of size upto 1cms can be treated with this technique. HEXApod RT system is specially designed to give that extra degrees of freedom , so that patient set up and positioning is very accurate. This is also a day care procedure , where in patient goes back home the same day .
INDICATED IN – Carcinoma prostate, Carcinoma lung, Metastatic Lung cancers Metaststic liver tumors , Primary Liver tumors , and metastatic bone tumors .
IGRT – IMAGE GUIDED RADIOTHERAPY
IGRT is a from of IMRT , where in to improve the delivery of treatment , it involves conformal radiation guided by a CT scan(CONE BEAM CT SCAN) , taken in the treatment room and the images are verified with the planning CT scans . Any errors in positioning can be immediately corrected . This is done to verify the treatment position .
IGRT is more advanced technique , which is combined with ABC for all tumors which move with respiration .
This is first of its kind in sahaydri hospitals, used in breast, lung and liver tumors .
INDICATED IN – LUNG TUMORS, PROSTATE CANCERS, BRAIN TUMORS,
