Abstract
Analysis of the human brain is most commonly performed using Magnetic Resonance Imaging (MRI) due to it being relatively fast and non-invasive. MRI technology leverages the fact that the human body is comprised mostly of water, using a strong magnetic field to align the hydrogen protons of the H2O molecules within the subject. A radio signal is used to excite those protons and is then turned off. As the protons relax, they release radio waves that are detected by the sensor, producing an image. The amount of time required for the atoms to return to equilibrium will be different for different types of body Analysis of the human brain is most commonly performed using Magnetic Resonance Imaging (MRI) due to it being relatively fast and non-‐‑invasive.1 MRI technology leverages the fact that the human body is comprised mostly of water, using a strong magnetic field to align the hydrogen protons of the H2O molecules within the subject. A radio signal is used to excite those protons and is then turned off. As the protons relax, they release radio waves that are detected by the sensor, producing an image. The amount of time required for the atoms to return to equilibrium will be different for different types of body tissue, so this is used to distinguish separate anatomical features. tissue, so this is used to distinguish separate anatomical features.
