Cobalt-60 for India (and developing countries): Still scope for large-scale deployment and need for developing, promoting & sustaining indigenous development Cobalt: Indigenous Machine Economic Factors � Telecobalt useful for cancers � Health budget < 2% of GNP prevalent in India (H & N, cervix, � Competing public health issues chest wall) & all palliative cases (2/3 rd cases) � Despite sustained & high � Rugged performer (workhorse) in economic growth rate, the high diverse conditions cost of imported Linacs & the � Low cost of installation, running, Telecobalt machines would remain & maintenance a deterrent for filling the shortfall � Indigenous technology is low- of 700 units within an acceptable cost, yet technically at par or even better at some parameters time frame
Innovations with Cobalt-60: How do we scale up? � Physical Compensator based precision radiotherapy � Multi-leaf Collimator (MLC) design for Cobalt-60 head � IGRT (Integration of MRI with Cobalt-60) � Adaptive Radiotherapy with Cobalt-60 Tomotherapy
Compensator plan vs MLC IMRT plan: Indistinguishable
Lesser MUs with compensator based IMRT Fluence transfer for milling
