Beams shaped to the three-dimensional outline of the target from a planning CT — the dependable foundation on which modern external-beam radiation is built.
3D-CRT is the foundation technique of modern radiation: beams individually shaped to the target's 3D form, planned on the patient's own CT anatomy.
Using a planning CT, the target and nearby organs are outlined in three dimensions, and each beam is shaped to match the target's profile from its direction. It conforms the dose far better than older two-dimensional methods.
3D-CRT is planned from a CT simulation and delivered as painless daily sessions. Dr. Bhatnagar selects between 3D-CRT and more complex techniques based on what each individual case genuinely needs.

No. For many straightforward targets it delivers an excellent plan with a shorter planning time. The technique is chosen to fit the case, not the other way round.
It varies with the site and intent, from a single session for pain relief to several weeks for curative treatment.

General information, not a substitute for a consultation. Your plan depends on your reports, stage and general health — discuss your case with Dr. Bhatnagar.
Bring your reports and scans for a consultation — he will tell you plainly whether radiation has a role.
