Define and explain the physics of five state of the art methods, of your choice,

Define and explain the physics of five state of the art methods, of your choice, that are used for medical imaging and/or therapy in 2022. Modern techniques can do much more than take a simple X-ray. The physics involved in your explanation will be the notions such as wavelength, frequency, power, source, imaging, and analysis. Describe what and how each method measures.
As a medical leader select two of those radiological methods predict with some quantitative evidence how they will evolve over the next five years.
