For example, the cost of a CT scanner can be as low as $65,000 for a refurbished one that produces only small images quickly. A larger and brand new CT scanner can run as high as $2.5 million.Prices are slightly higher for MRI machines, running up to about $3 million for a new machine.Ultrasound machines are much cheaper at $10,000-$200,000, depending on brand and type. larger and brand new CT scanner can run as high as $2.5 million.

1 Second law of thermodynamics: In a natural thermodynamic process, the sum of the entropies of the interacting thermodynamic systems increases. 2  Equivalently, perpetual motion machines of the second kind are impossible.
First Law of Thermodynamics. The law that heat is a form of energy, and the total amount of energy of all kinds in an isolated system is constant; it is an application of the principle of conservation of energy. Also known as conservation of energy.
