When kVp is increases exposure to the image receptor is increased with what kinds of imaging. The photosynthesis by phytoplankton in the oceans. With all other factors unchanged if OID is increased subject contrast in the remnant beam signal will.
An original issue discount OID is the discount in price from a bonds face value at the time a bond or other debt instrument is first issued. With all other factors unchanged if OID is increased subject contrast in the remnant beam signal will. May be affected indirectly but is not directly controlled by it.
Decrease as a direct result c. Increase the SID to compensate for the. A reduction in scatter radiation is likely to occur from which of the following.
Increased collimation a smaller field size reduces the amount of scatter produced by the tissue and therefore increases the image contrast because less. Which of the following would improve digital image quality. What examinations require a larger SID.
What type of distortion results from increase in OID size a grid usually is employed in which of the following circumstances when radiographing a large or dense body part. 40 SID 3 OID. Large matrix and increased pixel density 2.

Which of the following contrast media when added body decreases the tissue density of the body part. Size distortion is affected by. Which of the following will produce the largest image.
OID is unrelated to radiographic detail. Radiographic recorded detail is inversely related to OID. The ability of an imaging system to accurately display objects in two dimensions.
To increase recorded detail OID should be maximized. May be affected indirectly but is not directly controlled by it. The exposure rate will increase 3.
But only a 15 increase in kVp will increase the density 100. More scattered radiation will be produced 2. The sharpness of the image.
Which of the following factors has the greatest effect on radiographic density. No bc anatomy is 3-D and image is 2-D 63 The further away the OID how does it change the image size Larger is the image size 64 Magnification Factor. When do we use a long SID and why.
Radiographic contrast will increase A 1 only B 1 and 2 only C 2 and 3 only D 1 2 and 3. Decrease as a direct result c. An increase in size distortion.
