What is a foreshortening in medical terms?
[for-shor´ten-ing] a distortion that gives the appearance of decreased depth in an image that is being studied radiographically.
What is foreshortening in radiology?
Foreshortening is the result of overangulation of the x-ray beam. When foreshortening occurs when using the paralleling technique, the angulation of the x-ray beam is greater than the long axis plane of the teeth. This error can also occur if the receptor is not placed parallel to the long axis of the teeth.
What does foreshortening refer to?
Foreshortening refers to the technique of depicting an object or human body in a picture so as to produce an illusion of projection or extension in space.
What does elongated mean in medical terms?
1. the act or process of increasing in length. 2. a radiographic distortion in which the image is longer than what is being x-rayed.
What are the two components of atmospheric perspective?
There are two types of perspective – atmospheric and linear. As noted above, atmospheric perspective refers to how the atmosphere affects how we see things. Linear perspective on the other hand, refers to the relative size of objects and how an object appears smaller as it recedes into the distance.
What is quantum mottle caused by?
Quantum mottle is an inescapable artifact of radiologic imaging. It is caused by constraints in the number of x-rays at a specific strength passing through tissues of different densities and striking the film or display screen, which has an inherent speed.
What is magnification in radiography?
Magnification radiography is the purposeful production of an image larger than the object being studied. This technique can be utilized to image detail that is not resolvable by normal means.
What is foreshortening give an example?
A familiar example of foreshortening in the landscape would be that of a long, straight, flat road lined with trees. The two edges of the road appear to move towards each other as they reach into the distance. Foreshortening in a figure drawing or painting affects the proportions of the limbs and the body.
