IMRT, VMAT, and Stereotactic Radiotherapy: Choosing the Right Radiation Technique for Cancer Care
In the constantly changing world of cancer treatment, the gap between a patient’s complete healing and suffering from prolonged treatment side effects can be just a few millimetres of accurate targeting. As we gradually shift towards personalised medicine, the use of Advanced Precision Radiotherapy for Complex and Advanced Stage Cancers has emerged as the mainstay of successful treatment.
Those who want top-quality treatment can contact a Leading Radiation Expert at Yashoda Medicity, Ghaziabad, who will ensure they receive the most advanced technology. With a top Radiation Oncologist in Delhi NCR by their side, patients will be able to understand and navigate new treatments without stress or confusion.
The Evolution of Precision: Understanding Modern Radiotherapy
The field of oncology has evolved tremendously in recent years, and one of the most exciting areas is the use of radioisotopes in combination with highly precise beam delivery techniques for cancer treatment. Through radioactive decay and high, energy X, rays, doctors can now concentrate their radiation therapy on tumours while usually protecting the surrounding normal tissues.
Dr Rashmi Shukla, a distinguished professional with more than 16 years of experience, is known for her deep knowledge of these high-tech treatment methods IMRT, SBRT & VMAT. She is pushing the boundaries of what can be done for patients with very advanced cancers by working from the latest scientific research to a doctor and patient partnership at Yashoda Medicity.
Intensity-Modulated Radiation Therapy (IMRT): Sculpting the Beam
What is IMRT?
IMRT is a state-of-the-art radiation therapy method that precisely modulates the dose and shape of the radiation to the tumour. In contrast to conventional radiation, which uses uniform beams, IMRT treats the tumour as a 3D volume with varying densities.
How does IMRT Work?
IMRT radiotherapy employs a computer-controlled system that splits the radiation beam into numerous small “beamlets” of varying intensity. By varying these intensities and delivery angles, the system uses the radiation to match the tumour shape exactly, even if it is concave or adjacent to a vital organ.
Volumetric Modulated Arc Therapy (VMAT): Efficiency Meets Accuracy
What is VMAT?
VMAT, also known as Rapid Arc, is a revolutionary technique that merges the accuracy of IMRT with the fast delivery of radiation. Rather than coming to a halt at various angles, the radiation is delivered in a single, uninterrupted spin.
How does VMAT Work?
VMAT uses a linear accelerator (LINAC) that revolves 360 degrees around the patient. During the rotation, the device is continuously adjusting the beam’s intensity, the aperture’s shape, and the rotation speed. This way, a tumour gets a high dose from all the angles in a very short time.
What is Stereotactic Radiotherapy?
IMRT and VMAT techniques are designed to efficiently “sculpt” radiation beams to conform to the shape of a large target volume, whereas Stereotactic Radiotherapy can be considered as the “sniper rifle” of cancer treatment. It is a highly precise radiation treatment modality that can deliver very high radiation doses only to a small and clearly defined tumor target with sub-millimeter accuracy.
How It Works: The “Searchlight” Effect
Stereotactic radiotherapy is a technique in which a large number of small, thin radiation beams are precisely pointed at different angles.
- Separately, As each beam goes through healthy tissue, it is quite weak.
- Where the tumor is located: At the point where the cancer cells are, the beams converge (meet) exactly.
- The consequence: The tumor is given a very high, fatal dose of radiation, whereas the neighboring organs get only a tiny proportion of that dose.
Why Choose Advanced Precision Radiotherapy?
The main aim of a Radiation Oncologist in Delhi NCR is to open the “therapeutic window” as wide as possible, meaning the difference between killing the cancer and protecting the patient. They can use methods such as IGRT (Image-Guided Radiotherapy), Brachytherapy, or very advanced procedures such as Total Skin Electron Therapy (TSET) or Total Body Irradiation (TBI) to achieve that. This way, doctors like Dr. Rashmi Shukla can tailor the treatment plan to the biological signature of the disease.
