Physics
CMR uses the same basic principles as other MRI techniques with the addition of ECG gating. Most CMR uses only 1H nuclei MR, which are abundant in human tissue. By using magnetic fields and radiofrequency (RF) pulses, the patient's own 1H nuclei absorb and then emit energy, which can be measured and translated into images, without using ionising radiation.

Famous quotes containing the word physics:
“... it is as true in morals as in physics that all force is imperishable; therefore the consequences of a human action never cease.”
—Tennessee Claflin (1846–1923)
“The labor we delight in physics pain.”
—William Shakespeare (1564–1616)
“The pace of science forces the pace of technique. Theoretical physics forces atomic energy on us; the successful production of the fission bomb forces upon us the manufacture of the hydrogen bomb. We do not choose our problems, we do not choose our products; we are pushed, we are forced—by what? By a system which has no purpose and goal transcending it, and which makes man its appendix.”
—Erich Fromm (1900–1980)
