80% of global population, living in the Third World still remain deprived.
Hardly a few % of them, who are rich, get benefit of modern healthcare technology at huge costs
Motivation:
ECG & X-Ray invented more than 100 years back. How many get the benefits even today?
![Page 4: Local Solution with Global Potential](https://reader033.fdocuments.in/reader033/viewer/2022042707/58eeb26d1a28ab08058b45bb/html5/thumbnails/4.jpg)
Our efforts towards indigenous design and Innovation
Initially at department of Physics
Now atdepartment of
Biomedical Physics & Technology(established in 2008, initially offering PhD & Mphil only,
now offering Masters programmes in Medical Physics (Radiation related)
and Biomedical Engineering

Others starting FIM study:
• Warwick University, UK
• Kyung Hee University, Korea
• University of Oslo, Norway
A Swiss R&D company showed interest in developing the equipment for commercialisation, but we did not want take patent, so did not work out

We have to break away from the existing accepted norm of getting equipment from
the rich countries.
for global benefit,
We are not patenting our products!!Teach technology, manufacture and entrepreneurship to Third World scientists and engineers, ask them to produce the equipment in their own country and sell
![Page 51: Local Solution with Global Potential](https://reader033.fdocuments.in/reader033/viewer/2022042707/58eeb26d1a28ab08058b45bb/html5/thumbnails/51.jpg)
Technology innovators should become entrepreneurs
Businessmen cannot do this job
(wrong concept prevalent now)
