Linear Accelerators at Dharamshila Hospital is supported by the world′s best Radiotherapy Treatment Planning Systems like Monaco with Monte Carlo Algorithm, ERGO++, CMS Xio and Eclipse.
Before Radiation Therapy, a detailed custom made computerized Treatment Planning is worked out for each and every patient. It is an elaborate process requiring preparation of cast/mould for immobilization of the patient and Contrast CT Scanning at 3-5mm cuts of the tumour. CT images are directly transferred to the Treatment Planning System. On the basis of the images, contouring of the tumour is made on each section of CT scan along with critical structures. A prescription is worked out on the basis of tumour volume, nature of tumour and general condition of the patient. Physicist works out optimal field projection to the tumour area with minimal radiation to critical structures through Varian/ Elekta Software developed for each type of treatment protocol like IMRT, IGRT, SBRT, SRS / SRT, VMAT and Respiratory Gating.
These plans are jointly evaluated by Radiation Oncologist and Physicist and the best plan is finalized for execution of treatment. Patient is then taken up for treatment. Once again the position verification (conformation of accurate treatment position) is done through 3D CT imaging or portal imaging on KV or MV basis which is incorporated in the Linear Accelerator.
