Which of the following method is NOT used for the assessment of mitral valve area with echocardiography?
A. Continuity equation
B. Hooke’s law
C. Plainimetry method
D. Pressure-half time method
Answer: B
In mechanics, and physics, Hooke’s law of elasticity is an approximation that states that the extension of a spring is in direct proportion with the load added to it as long as this load does not exceed the elastic limit. Materials for which Hooke’s law is a useful approximation are known as linear-elastic or "Hookean" materials.
The lungs, as an elastic structure, over a limited range of lung volume, obey Hooke’s law.
