A magnetic resonance imaging instrument (MRI scanner), or "nuclear magnetic resonance imaging" scanner as it was originally known, uses powerful magnets to polarize and excite hydrogen nuclei (i.e., single protons) of water molecules in human tissue, producing a detectable signal which is spatially encoded, resulting in images of the body.

[3] Their healthcare delivery model was centered on assessing each senior's needs on an individual level in order to coordinate appropriately for each unique case ...
In conventional CT machines, an X-ray tube and detector are physically rotated behind a circular shroud (see the image above right). An alternative, short lived design, known as electron beam tomography (EBT), used electromagnetic deflection of an electron beam within a very large conical X-ray tube and a stationary array of detectors to achieve very high temporal resolution, for imaging of ...

Hence, competition in a free market is a consequence of the conditions of a free market, including that market participants not be obstructed from following their profit motive.
