The MRI was the most advanced way of diagnosing what patients were suffering from. It was cutting edge technology that gave very detailed images of the human body. Technology moves forward and advances are made.
Macquarie University with CSIC and the Institute of Photonic Sciences (ICFO) have found a way of producing images even clearer than MRI. It is done by using artificial atoms and nitrogen doped diamond nanoparticles. Extremely weak magnetic fields in the human body can now be detected. MRI resolution is millimetric. The new system "sees" down to a millionth of a millimeter.
This technique is not invasive. It will provide an understanding of intracellular processes. The problem with the new diagnostic system is that very temperatures are required to make it work. Artificial atoms are encapsulated in a diamond crystal. They can be manipulated by lasers, dragging atoms above the surface for medical diagnosis.
