In a groundbreaking development for cancer care, India has installed an advanced medical system that promises to transform how radiation therapy is administered. The Elekta Unity MR Linac, a first-of-its-kind integrated system combining real-time Magnetic Resonance Imaging (MRI) with radiation therapy, is now operational at Yashoda Medicity, Ghaziabad.
The Elekta Unity system successfully merges two critical components in cancer treatment: an MRI scanner and a radiation therapy machine. This integration allows for precise imaging of tumours and surrounding tissues in real time, significantly streamlining the radiation treatment process. Traditional methods generally rely on CT scans, which often lack the clarity needed for soft tissue evaluation. The MRI component of the Elekta Unity system provides high-resolution images that are crucial for accurately targeting cancer cells while minimizing damage to healthy organs.
One of the standout features of this technology is the Comprehensive Motion Management (CMM) system. This allows the machine to track even the slightest movements of the patient during treatment, adjusting the radiation dose accordingly. For example, if a patient breathes or shifts slightly, the machine can compensate to ensure precise dosage is delivered to the affected area.
This adaptive mechanism makes it possible for oncology specialists to adjust treatment plans on a daily basis, catering to the dynamic nature of a patient’s anatomy. Consequently, this leads to more personalized and effective cancer treatments, particularly beneficial for those with small tumours or those requiring frequent radiation sessions.
Dr. Upasana Arora, Managing Director of Yashoda Medicity, emphasized the transformative impact of this technology, stating, “We can now personalize each radiation session in real time, improving outcomes and reducing side effects.” The speed and accuracy of the Elekta Unity system enable quicker treatment sessions, which not only enhance patient comfort but also support hypo-fractionated treatment — delivering higher radiation doses in fewer sessions.
The new system also facilitates remote treatment planning, allowing healthcare professionals to design and assess treatment plans without being physically present at the medical facility. This flexibility can improve operational efficiency and patient care, especially in an era when telehealth has gained prominence.
As India faces a rising tide of cancer cases — with over 1.4 million new cases reported annually — the introduction of the Elekta Unity MR Linac sets a new benchmark in oncology. Dr. Gagan Saini, Vice Chairman and Head of Radiation & Oncology at Yashoda Medicity, noted that the technology is timely and necessary for enhancing care standards as treatment needs evolve.
Looking ahead, this innovative approach opens avenues for future developments in cancer treatment methodologies, such as Biology-Guided Radiotherapy (BgRT), which aims to further individualize patient care by aligning treatment with biological markers.
