What is the meaning of opacification?

1. opacification – the process of becoming cloudy or opaque. natural action, natural process, action, activity – a process existing in or produced by nature (rather than by the intent of human beings); “the action of natural forces”; “volcanic activity”

What is opacity in chest xray?

Pulmonary opacification represents the result of a decrease in the ratio of gas to soft tissue (blood, lung parenchyma and stroma) in the lung. When reviewing an area of increased attenuation (opacification) on a chest radiograph or CT it is vital to determine where the opacification is.

What is superposition of waves?

The principle of superposition may be applied to waves whenever two (or more) waves travelling through the same medium at the same time. … The net displacement of the medium at any point in space or time, is simply the sum of the individual wave displacements.

What is meant by opacity?

1a : obscurity of sense : unintelligibility. b : the quality or state of being mentally obtuse : dullness. 2 : the quality or state of a body that makes it impervious to the rays of light broadly : the relative capacity of matter to obstruct the transmission of radiant energy.

What subordinate means?

noun. the act of placing in a lower rank or position: The refusal to allow women to be educated was part of society’s subordination of women to men. the act subordinating, or of making dependent, secondary, or subservient. the condition of being subordinated, or made dependent, secondary, or subservient.

What happens as a result of constructive interference?

Constructive interference occurs when the maxima of two waves add together (the two waves are in phase), so that the amplitude of the resulting wave is equal to the sum of the individual amplitudes. Equivalently, the minima of the waves would be aligned.

What does Supercalifragilisticexpialidocious mean?

adjective. informal. Extraordinarily good; wonderful. ‘the only word to characterize Kepler’s discoveries was ‘Supercalifragilisticexpialidocious” ‘a supercalifragilistic day of fun’

What does congruent mean?

Congruent means same shape and same size. So congruent has to do with comparing two figures, and equivalent means two expressions are equal. So to say two line segments are congruent relates to the measures of the two lines are equal.

What does superimposed mean in medical terms?

Superimpose means laying one thing on top of another. It’s often used to describe images in a photo collage — like the superimposed image of a skyscraper on the surface of the moon.

What does opacity refer to with a radiograph?

1. A lack of transparency; an opaque or nontransparent area. 2. On a radiograph, a more transparent area is interpreted as an opacity to x-rays in the body.

What is the difference between Superpose and superimpose?

superposed – Place (something) on or above something else, esp. so that they coincide: “superposed triangles”. superimpose – Place or lay (one thing) over another, typically so that both are still evident.

What causes superimposition?

The culprit is the superposition of two waves of similar but not identical frequencies. When two waves of similar frequency arrive at the same point and superimpose, they alternately constructively and destructively interfere. This alternating is known as a beat because it produces an unpleasant pulsing sound.

What happens when two frequencies collide?

Constructive interference describes what happens when sound waves that are of equal frequency and phase add together to form a wave of larger amplitude. … When sound waves of different frequencies collide, the result is beating because part of the wave interferes constructively and part interferes destructively.

What is the principle of superposition answers?

1 Answer. Principle of superposition states that when two or more waves meet at a point, the resultant wave has a displacement which is the algebraic sum of the displacements of each wave.
