About Medical Imaging
Medical imaging is the technique and process of creating visual representations of the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues.

Quantum dots: TV screen crystals win Chemistry Nobel Prize
By Georgina RannardScience reporter, BBC News
The Nobel Prize for chemistry has been awarded to three scientists for their work in developing what are called quantum dots.
People may have come across these Tiny crystals in their QLED TV sets where the nanoparticles create colour.
They are also used in Medical Imaging to guide surgeons, in better targeting of cancer drugs, and in solar panels.
Winners Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov will share the 11m Swedish Krona (£824,000) prize.
Their names were released accidentally in a press release from Sweden's Royal Academy of Sciences, hours before the official announcement on Wednesday morning.
The Academy said it was trying to understand why The Names were released early. " This is of course very unfortunate. We deeply regret What Happened , " The Academy chair said.
He insisted that The Final decision on The Winners was not made until The Academy met just before the official announcement.
" It's quite an honour, " prize-winner Moungi G. Bawendi told The Academy in a phone call minutes after The Names were announced.
He Said he was " very surprised, sleepy, shocked and very honoured" adding that he had not heard The News before The Academy rang him.
Quantum dots are extremely Tiny - just a few millionths of a millimetre across.
Their exact size determines The Colour of light they emit when given energy. Smaller quantum dots are blue, and bigger dots are yellow and red.
" For a long time nobody thought you could make such small particles, " but The Winners this year managed to do just that, The Academy said when announcing The Prize .
The three scientists are US-based. Russian physicist Alexei I. Ekimov is credited with first discovering quantum dots in the 1980s, and US chemist Louis E. Brus then realised The Crystals could be developed floating in fluid.
Paris-born Moungi G. Bawendi invented a method for making the particles in a much more controlled way, meaning they could be more easily created.
" Quantum dots are thus bringing The Greatest benefit to humankind, " said The Royal Swedish Academy of Sciences.
" Researchers believe that in The Future they could contribute to flexible electronics, Tiny sensors, thinner solar cells and encrypted quantum Communication - so we have just started exploring the potential of these Tiny particles, " it added.
