MRI Machines Can Cost 100 Times Less, Thanks To This Discovery In Mumbai

The scientists in Mumbai have discovered that metal Bismuth has superconducting properties.

  • Tata Institute of Fundamental Research found Bismuth is a superconductor
  • The research team says application could take long but will lower costs
  • The current cost of a good MRI machine is Rs 10 crore

Mumbai/New Delhi: A scientific breakthrough in Mumbai can bring down the cost of Magnetic Resonance Imaging or MRI machines by 100 times, claim scientists.

A team of scientists from Tata Institute of Fundamental Research has discovered that metal Bismuth can conduct electricity without any resistance, making it a superconductor.

The superconducting property, the scientists say, is a unique state of matter that has many applications and is very costly to achieve. The discovery is being touted to rewrite a four-decade old Nobel Prize winning theory that explains how metals become superconducting.

Prof S Ramakrishnan, Tata Institute of Fundamental Research, Mumbai, says, “We have discovered superconductivity in Bismuth and to explain this, we need a new theory and a new mechanism. Once that comes out, we will probably have a new class of superconductors.”

After unsuccessful global efforts for decades, the team calls this finding a fundamental scientific breakthrough. In order to achieve this, the scientists placed metallic Bismuth in very cold temperature to make it lose all resistance to electricity.

Currently, the MRI machines use superconductors made of an alloy called Niobium-Titanium and a good machine costs Rs 10 crore.

The team says that the applications of the discovery could take long but it promises to lower the cost of high end diagnostic machines.

Dr Arumugam Thamizhavel, Assistant Professor, Tata Institute of Fundamental Research, Mumbai, says, “Currently, there are no theories that can explain Bismuth’s superconductivity. This is a different type of superconductivity as compared to others. The theorists are working on it now and new theories may come out. Right now, MRI scans are possible only because of a superconducting magnet, so this discovery can find its application in some years.”

According to the scientists, the MRI machines use superconductors made of an alloy called Niobium-Titanium and if superconductors of Bismuth will be used, the cost of an MRI machine could come down by a 100 times.

The current cost of a good MRI machine is Rs 10 crore.

The discovery has been published in the current issue of ‘Science’ journal (Washington DC).

  1. Hi there, i read your blog from time to time and i own a
    similar one and i was just wondering if you get a lot of spam responses?

    If so how do you protect against it, any plugin or anything you
    can recommend? I get so much lately it’s driving me mad so any help
    is very much appreciated.

  2. So according to Pallava Bagla calculation, MRI machine will be available at 10 Lakh rupees if Bismuth is used as superconductor in MRI machine. Wow.

  3. Congratulation!. I hope this works very well and it will bring a revolution in the Scientific community and will be benefitted by millions all over the world.
    Great task from India by Indian.

  4. Who writes these articles really? How can something cost 100 times less? So lets say a pen costs Rs.10. If it costs 100 times less then the cost is is Rs.1000 less than the original price? So patients will get paid Rs.990 for getting the procedures done?

  5. i hope the machine is made in India and can serve Indians. This pilferage of our scientific outputs have gone unchecked for decades.
