What is spin also known as?
What is angular momentum also known as?
What greek letter is this: γ
What does γ mean in MRI?
What occurs to the spin of protons when a magnetic field is applied?
The spins will align and spin either up or down in relation to the field
Why aren’t all protons in the low energy alignment when in a magnetic field
thermal energy bounces them between states
How can we change the spin state of protons?
Hit them with a photon that has the right amount of energy to increase them to the higher energy state
What greek letter is this: ω
What does ω mean in MRI?
What is the symbol for the Larmor Frequency
What is the Larmor frequency
rate of precession of the magnetic moment of the proton around the external magnetic field. The frequency of precession is related to the strength of the magnetic field,
What is the Larmour equation?
ω = γB
B is magnetic field strength
What’s the name of the distribution of proton energy levels due to thermodynamics in nuclear resonance?
The Boltzmann distribution
FID acronym in MRI?
Free induction decay
What’s it called when protons are precessing in synchronicity?
