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 This law helps define the notion of temperature. 2  First law of thermodynamics: When energy passes, as work, as heat, or with matter, into or out from a system, its internal energy changes in accord with the law of conservation of energy. 3  Equivalently, perpetual motion machines of the first kind are impossible.
The First Law Of Thermodynamics. The first law of thermodynamics can be captured in the following equation, which states that the energy of the universe is constant. Energy can be transferred from the system to its surroundings, or vice versa, but it can't be created or destroyed. A more useful form of the first law describes how energy is conserved.
