MRI’s Explained – Open vs. Closed Operating Systems

Magnetic resonance imaging (MRI) didn’t start as the technology we now commonly know. Researchers Felix Bloch and Edward Purcell first discovered the magnetic resonance phenomena in 1946 and later harnessed the abilities of magnetic resonance to analyze chemicals, leading to their Nobel Prize in 1952. Later on, scientists discovered the same technique could be used to visualize different human tissues. By 1973, aided by the rapid technological progression of computers, researchers developed the MRI that we now use today. Then, in 2003, the MRI led to another Nobel Prize, this time awarded to researchers Paul Lauterbur and Peter Mansfield for developing MRI as a diagnostic tool. What is an MRI? An MRI uses a strong magnetic field and directs the field at a specific area of the object or person of interest. As the magnetic field enters different tissues and fluids within the body, hydrogen atoms become excited similarly to how a smaller magnet becomes excited as a larger magnet inches closer. Depending on the tissue or fluid that the hydrogen atoms are in, the atoms return to a resting state at different rates as the magnetic field is turned on and off several times. This allows a computer to analyze the [...]
