Thickness, composition and pathology are a part of which factor

This is the general size of a patient

The technique on most operating consoles is based on which body type

These patients are thin but healthy

this refers to the fidelity with which the anatomical structure that is being examined is imaged on the radiograph

the ability to image two separate objects and visually distinguish one from the other

This is when the objects on the image are larger than the objects that they represent

This is unequal magnification of different portions of the same objects that they represent

This is reduction in image size due to angle or inclination of the object

An image that is made to appear longer than it really is because of the incline of the object is not located on the central beam

This is a radiograph that faithfully reproduces structure and tissues

The most important characteristics of radiographic quality are

Refers to the ability to image small objects that have high subject contrast such as bone-soft tissue

This is the random fluctuation in the optical density of the image

lower noise results in improved

Radiographic contrast is the product of what two separate factors?

If the optical density differences are small and are not distinct the radiograph is of a _____ contrast

This is determined by the size, shape and x-ray attenuating characteristics of the anatomy that is being imaged and the energy of the x-ray beam

more matter more_____

The most commonly used method of restricting the primary beam field size is

Which of the following are image quality factors

This is the language of radiography

What are the two categories of image detail

increasing SID has what effect on magnification

What is the formula for magnification factor

What two factors minimize magnification

What conditions contribute to image distortion

thick objects are more or less distorted than thin objects

In order to reduce distortion, the object plane and the image plane should be_______

a thick body part attenuates _____ number of x-rays than a thin body part

how can we minimize the amount of scatter that reaches the IR?

where are grids placed

This is the most important influencing factor for subject contrast and can be controlled by the technologist

a low kVp results in ____ subject contrast

movement of the patient during the x-ray exposure results in

This is the main cause of motion blur

voluntary and involuntary are types of

All exposure times should be

A high kVp results in a greater

a high kVp causes increased ____ resulting in reduced contrast

What is the primary controller of optical density (OD)

How does increasing mAs affect quantity

what affect does a high mAs have on noise

as kVp increases what happens to photoelectric effect

as kVp is increased, what happens to compton scatter

As kVp is increased what happens to the number of photons that reach the IR

As kVp is increased what happens what happens to the number of photons that interact with matter

an increase in kVp creates what scale of contrast

the thicker the tissue the ____ the kVp that is necessary

when more photons are absorbed in the tissue what is the affect on the IR exposure

If I increase kVp by 5%, what do I do to mAs in order to maintain exposure to the IR

we use this item to measure our body part thickness

In order to determine technique, where should I measure body part thickness

A chest has what type of subject contrast

An abdomen has what type of subject contrast

What are the two classifications of pathology

osteoporosis is what type of pathology

destructive pathologies are more____

additive pathologies are more

Which of the following are types of image artifacts
