Magnetic Resonance Imaging: Market Trends

Darshana De - Frost & Sullivan Research Analyst

MRI systems represent one of the strongest markets in the medical imaging industry. MRI is a non-invasive method of using a magnetic field and radio waves to create detailed images of the inside of the human body. It was originally used to view the central nervous system. With time, its use has expanded to study the internal anatomical structures of the human body.

The hydrogen protons inside our body have magnetic property which, when placed inside a large magnet, like the MRI machine, can be magnetised. An additional magnetic field introduced in the form of pulses that excite the hydrogen protons to higher energy level interact with the tissues giving rise to electromagnetic signals. These are then acquired and converted into images according to their energy content. Ever since the technology came into existence, it has been considered as a ‘miracle technology’.
