Size distortion has to do with magnification. Increased SID decreases distortion especially is it's within the appropriate range for the part. (ie 40/72). Increasing OID is most detrimental and increases distortion. Angling the tube increases SID HOWEVER, it increases distortion. Angling the tube also increases distortion for shape. If the part and IR are not properly *aligned or *centered, this also increases distortion. Shape distortion has to do with elongating or foreshortening a part on the image.

What is chromatic aberrations?
the variation of either the focal length or the magnification of a lens system with different wavelengths of light, characterized by prismatic coloring at the edges of the optical image and color distortion within it.
What did the student most likely do to cause the different between the two views?
The student most likely changed their perspective or gained new information that influenced their change in views. This could include a shift in beliefs, exposure to different viewpoints, or a deeper understanding of the subject matter.
What happens when the x-ray tube is to close to the chest for an x-ray?
WHILE TAKING A PA VIEW OF CHEST DISTANCE BETWEEN XRAY TUBE AND FILM IS ABOUT 6 FT SO AS TO DECREASE THE MAGNIFICATION AND INCREASE THE SHARPNESS OF IMAGE WHEREAS AN AP VIEW WHICH IS TAKEN AT LESSER DISTANCE THERE IS INCREASED MAGNIFICATION AND DECREASED SHARPNESS. THEREFORE WHEN the X-ray tube is to close to the chest for an X-ray IT CAUSES 1 INCREASED MAGNIFICATION 2 DECREASED SHARPNESS
What type of fading cause serious distortion of modulating signal?
selective fading
