At Yashoda Medicity, precision oncology is significantly enhanced with the Elekta Unity MR-Linac, a state-of-the-art system that integrates a high-field 1.5 Tesla MRI with a linear accelerator. This advanced platform enables highly precise radiation delivery while simultaneously visualising the tumour and surrounding organs in real time through high-resolution MRI imaging before and during each treatment session.
By leveraging superior soft tissue visualisation, the system enables clinicians to account for daily anatomical variations, including changes in tumour position and internal organ motion. This is particularly critical in abdominal and pelvic cancers such as prostate, pancreatic, liver, and gynaecological tumours, where continuous internal movement can significantly impact treatment accuracy.
A key advantage of the system is its online adaptive radiotherapy capability, which allows treatment plans by Dr. Gagan Saini to be modified on the same day based on real-time imaging. This ensures that radiation delivery is continuously tailored to the patient’s current anatomy, improving targeting precision while better protecting surrounding healthy tissues. The system also enables real-time tumour tracking during treatment, allowing clinicians to monitor motion as it occurs and adjust accordingly for maximum accuracy. In selected cases, it can reduce or eliminate the need for invasive fiducial markers, depending on clinical requirements and treatment site.
With its MRI-guided workflow, Elekta Unity provides exceptional soft-tissue contrast without reliance on ionising imaging for setup, enabling clearer visualisation of tumours and organs at risk. This contributes to improved organ-at-risk sparing through daily replanning and highly refined dose delivery.
The system supports advanced treatment techniques such as stereotactic radiosurgery (SRS) and stereotactic body radiotherapy (SBRT/SRT), which deliver highly focused radiation doses with sub-millimetre precision. These approaches are designed to minimise exposure to adjacent healthy tissues while improving treatment efficiency. SRS typically delivers treatment in a single session, while SBRT/SRT is delivered over a few fractions, significantly reducing overall treatment duration compared to conventional radiotherapy schedules. This improves patient convenience, reduces hospital visits, and enhances treatment compliance.
With its integrated MRI-guided adaptive capability, Elekta Unity MR-Linac enables precise targeting of complex and mobile tumours in organs such as the lung, liver, pancreas, and pelvis. The use of daily diagnostic-quality MR imaging ensures continuous visualisation, adaptive refinement, and highly individualised treatment delivery, supporting advanced and patient-centric cancer care at Yashoda Medicity.
