A small number of very precise, high-dose treatments to a well-defined target in the body — concentrating the dose where it counts, with steep fall-off around it.
SBRT delivers a high, ablative dose to a small, clearly-defined target in just a few sessions — precision radiation, compressed into days rather than weeks.
Where conventional radiation spreads dose over many small daily fractions, SBRT delivers a much higher dose per session to a tightly-defined target, in typically one to five treatments. It depends on rigorous immobilisation and image guidance.
Because the dose per session is high, planning and verification are exacting. Dr. Bhatnagar will assess whether your tumour's size, site and surroundings make SBRT a suitable option.
Stereotactic body radiotherapy delivers a small number of very precise, high-dose treatments to a well-defined tumour, with the dose falling away steeply just outside it.
Usually between one and five, compared with several weeks for a conventional course.
Selected early lung tumours, liver lesions, spinal and other bone deposits, and some prostate cancers — where the target is small and clearly defined.
The treatment is painless and no anaesthesia is required, though immobilisation devices are used to keep you perfectly still.

Bring your reports and scans for a consultation — he will tell you plainly whether radiation has a role.
