Batra Hospital and Medical Research Centre, a super speciality hospital, providing comprehensive tertiary care under one roof. Cancer Centre is one of the leading department providing all three specialities (Medical, Radiation & Surgical) with highest standards. Medical Oncology department, offers cancer care with chemotherapy and targeted therapies as part of Neo-adjuvant (before surgery or radical radiotherapy), adjuvant therapy (after surgery / radical radiation) and palliative settings.
At Batra Cancer Centre, we use many standard radiation treatments in the ongoing fight against cancer. One of the more commonly used treatments available is external beam irradiation, also known as external beam radiation therapy.
External beam irradiation uses a sophisticated electronic machine to precisely aim and fire high doses of radiation at a cancerous tumor. This machine works from outside the patients body and moves around the patient without actually touching them.
Our patients usually receive daily treatment sessions over the course of several weeks. At very high doses, the treatments work because the high-energy radiation rays destroy cancer cells and shrink tumors.
Radiation treatments we offer include:
Intensity Modulated Radiation Therapy
Intensity modulated radiation therapy, also known as IMRT, uses hundreds of tiny radiation micro-beams of different intensities to deliver highly focused radiation directly into a tumor.
Intensity Modulated Radiation Therapy (IMRT)
At Batra Cancer Centre we afford our patients the most advanced systems of radiation treatment available today. Intensity modulated radiation therapy, also known as IMRT, is one such treatment. Hundreds of tiny radiation micro-beams of different intensities are carefully calculated and precisely sculpted in order to deliver highly focused radiation directly into the tumor.
The preciseness of this technique allows for the delivery of maximum dosages while sparing the healthy surrounding tissue. This is an “organ sparing” treatment which minimizes the amount of radiation to normal tissues surrounding the area being treated. IMRT allows us to combat tumors more specifically and intelligently than ever before. The effect is far less traumatic to our patients, with minimal damage to the bodys healthy tissue.
Image-Guided Radiation Therapy
IGRT or image-guided radiation therapy allows physicians to see and analyze tumors in real time, offering them unparalleled tumor control and sparing normal tissue from unnecessary radiation exposure.
Image-Guided Radiation Therapy (IGRT)
During image-guided radiation therapy (IGRT), repeated image scans are made to create a dynamic picture of the tumor.
This allows our physicians to see and analyze tumors in real time, offering them unparalleled tumor control and sparing normal tissue. The images are fed into computers to assist in guiding the radiation beam and to precisely follow the tumors motion. This is useful, for example, with cancers of organs that move with respiration.
IGRT images allow us to recognize changes in the size and location of tumors and to adjust the position of the patient during treatment or to make changes to the radiation plan. These image scans increase the accuracy of the radiation so the dose conforms to the tumor target and radiation exposure to healthy tissue is reduced.
Respiratory gating treats cancerous tumors with a high dose of radiation while sparing healthy tissue. This technology synchronizes precise doses of radiation with the patients own respiratory cycle so that radiation is delivered only when the tumor is in the treatment field. Learn about respiratory gating.
Respiratory gating treats cancerous tumors with a high dose of radiation while sparing healthy tissue, and is one of the latest advancements in radiation oncology available at Batra Cancer Centre. This technology synchronizes precise doses of radiation with the patients own respiratory cycle so that radiation is delivered only when the tumor is in the treatment field.
Respiratory gating is used to treat adult lung, liver, pancreatic and stomach cancers. When you breathe, internal organs can move as much as several centimeters causing tumors to move in and out of the radiation treatment field. Using the 4D image simulation, our doctors can build a model of your internal anatomy.
Batra Cancer Centres radiation oncologists and physicists use the model to pinpoint the location of the tumor. Once the location is established, our doctors determine the treatment objectives and review many care options to calculate the optimal arrangement and dose of radiation beams.
Rapid Arc Radiation Therapy
RapidArc radiotherapy technology is revolutionizing care for cancer patients. Its more precise than conventional radiotherapy and reduces what used to be a 10-15 minute treatment period down to two minutes. Learn more about Rapid Arc Radiation Therapy.
RapidArc Radiation Therapy
RapidArc™ radiotherapy technology is a new approach to image-guided, intensity-modulated radiation therapy (IGRT/IMRT) that delivers precise treatments in shorter times than conventional IMRT.
RapidArc represents a major medical advance and is more comfortable for patients because they spend less time in their daily treatments. A fast, precise RapidArc treatment takes 80% less time. Patients can be in and out of treatment quickly and return to their daily routine.
RapidArc rotates 360 degrees around the patient, enabling the very small beams with varying intensity to be aimed at the tumor from multiple angles. Unlike helical IMRT treatments or other forms of radiation therapy, with RapidArc the radiation treatment being delivered to the patient can be modulated continuously throughout treatment. This means that higher doses of radiation are delivered to hit the tumor harder, and less radiation is delivered to surrounding healthy tissue.
Prostate Rapid Arc Plan
RapidArc treatments are delivered using a Varian Linear accelerator outfitted with imaging capabilities. The RapidArc imaging capabilities let the clinician see the location of the tumor in three dimensions before treatment. If the cancer has moved due to physical changes, treatment can be adjusted so the patient receives a precise treatment.
RapidArc™ provides patients with:
Faster treatment times
Patients spend less time on the treatment table and in the IU Health Cancer Radiation Centers, and more time at home with their loved ones. Increased treatment accuracy We can target the tumor with more precision delivering more radiation directly to the cancerous cells, which can help destroy the cancer more quickly.
Better protection of healthy tissue
Because RapidArc™ is able to so precisely shape the radiation beam to the tumor, the healthy tissues surrounding the cancer receive less radiation, which can lead to fewer side effects following treatment. This is especially important when treating cancers of the head, neck and prostate.
Patient Benefits of RapidArc™
RapidArc™ System radiotherapy technology is revolutionizing care for cancer patients. It is more precise than conventional radiotherapy and reduces what used to be a 10-15 minute treatment period to two minutes, up to eight times as fast.
Patients barely realize they are being treated; they walk in and walk out as if nothing has happened. In addition to providing a more efficient treatment time span and less discomfort to patients, RapidArc™ reduces the chance of tumor movement during treatment, decreases the actual dose of radiation and the scattering of radiation outside the tumor and preserves more healthy tissue than conventional radiotherapy.
Batra Cancer Centres physicians provide the high quality images through concise, multi-faceted x-ray capabilities of the upgraded Varian Medical Systems CLINAC 2100C™ System. Batra Cancer Centre has upgraded CLINAC2100C™ System units with RapidArc™ in year 2011. Using this technology, RapidArc™ calculates the location, distance and density of the tumor to deliver intensity modulated radiation therapy (IMRT) rapidly to the tumor location. RapidArc™ delivers the radiation treatment while circling around the patient, using a beam with pinpoint accuracy to deliver the dose.
With 180 possible stops around the 360-degree arc and customized doses at various angles, the number of possible treatment solutions becomes infinite.
In 2014, Batra Cancer Centre planning to install TrueBeam™, a new Varian radiation therapy device that enables patients with reoccurring cancer to be treated.
Stereotactic Body Radiation Therapy
Stereotactic body radiation therapy (SBRT) is used for treating tumors that are present in the body, outside the brain and spinal cord. It delivers radiation to a tumor using special equipment for positioning patients with precise accuracy. Read about SBRT here.
Stereotactic Body Radiation Therapy (SBRT)
At Batra Cancer Centre, stereotactic body radiation therapy (SBRT) is used to deliver radiation to a tumor using special equipment to position patients with precise accuracy.
SBRT is used for treating tumors that are present in the body, outside the brain and spinal cord. SBRT is suited for treating small isolated tumors in the organs such as cancers in the liver or lungs. These tumors are more difficult to target accurately since they are more likely to move along with the normal motion of the body. Therefore, the total radiation dosage is divided into smaller doses which are given over several days in order to avoid damaging normal tissue with a single high dose of radiation.
