  • The previous chapter presents methods for representing a class of dynamic systems with relatively small numbers of components, such as a harmonic resonator with one mass and spring. The results are models for deterministic mechanics, in which the state of every component of the system is represented and propagated explicitly. Another approach has been developed for extremely large dynamic systems, such as the ensemble of gas molecules in a reaction chamber.

  • The field of medical imaging is advancing at a rapid pace. Imaging modalities like x-ray radiography, x-ray computed tomography (CT), ultrasound, nuclear imaging, magnetic resonance imaging (MRI), and optical imaging have been used in biology and medicine to visualize anatomical structures as large as the lung and liver and as small as molecules. Ultrasound is considered the most cost-effective among them. It is used routinely in hospitals and clinics for diagnosing a variety of diseases.
