Stereotactic Body Radio Therapy (SBRT)
Stereotactic Body Radiotherapy (SBRT), also known as Stereotactic Ablative Radiotherapy (SABR), is an advanced form of radiation therapy used to treat tumors with high precision. Unlike conventional radiation therapy, which delivers radiation over several sessions, SBRT delivers a highly focused, intense dose of radiation to the tumor in just a few sessions or even in a single session. Dr. Rajender has expertise in stereotactic body radiation therapy in Baraut. Dr. Rajender has 25 years of experience in this field.
Here’s how it works:
Imaging: Before treatment begins, imaging techniques such as CT scans, MRI, or PET scans are used to precisely locate the tumor and map its size, shape, and location relative to surrounding organs and tissues.
Treatment Planning: Using the imaging data, a treatment plan is developed to determine the optimal angles and doses of radiation. Advanced software algorithms are employed to calculate the exact radiation doses needed to target the tumor while minimizing exposure to healthy surrounding tissues.
Delivery of Radiation: During treatment, the patient is positioned on a specialized treatment table. High-energy X-ray beams or other radiation sources are then precisely directed at the tumor from multiple angles. The beams converge on the tumor, delivering a highly concentrated dose of radiation while sparing nearby healthy tissues.
Motion Management: Since SBRT requires high precision, any movement of the tumor or surrounding organs during treatment can affect its accuracy. Techniques such as real-time tumor tracking, breath-holding, or using immobilization devices help ensure that the tumor remains in the same position throughout the treatment session.
Monitoring and Follow-up: After treatment, patients are monitored closely to assess their response and any potential side effects. Follow-up imaging scans are performed to evaluate the tumor’s response to treatment and to check for any signs of recurrence.
SBRT is particularly effective for treating small to medium-sized tumors in various parts of the body, including the lungs, liver, spine, prostate, and pancreas. It offers several advantages over traditional radiation therapy, including shorter treatment duration, fewer side effects, and comparable or improved tumor control rates. However, not all patients or tumor types are suitable for SBRT, and treatment decisions should be made in consultation with a radiation oncologist experienced in this technique. As we know, Dr. Rajander is one of the best stereotactic body radiosurgery in Meerut.
