Harmonic analysis, or fourier transform, is the branch of mathematics that studies functions by deconstructing functions into simple building blocks. The materials learned in this branch can be applied to many different fields besides mathematics, including engineering, physics, applied mathematics, chemistry, signal processing, astronomy, optics, and more. Out of the possible fields, I chose to study the use of harmonic analysis in its application on medical imaging devices, such as X-rays and electrocardiographs (ECG). Electrocardiography is a transthoracic interpretation of the electrical activity of the heart over time, and is captured through skin electrodes. These skin electrodes are placed at specific points on the skin, and measure electrical impulses that travel to the heart. The results are displayed on an electrocardiogram, and indicate the rate of muscle fiber contraction.
