Imaging Flashcards
Particles of ionizing energy directed through the body towards a sensitive film
X-rays
Ability of rays to pass through body parts is dependent upon the _____ and composition of the tissues in the region
Density
The areas where the xray beams are absorbed and not transferring through the film will turn out ____ in the image, and that is known as ______
White; radiopaque
The more radiopaque an image is, the (higher/lower) the radio density is of the structure that the xray could not get through.
Higher
The colour that will appear on the xray if the x-rays pass through tissues in the body
Black
The opposite of radiopaque is ____
Radiolucent
Organize these four levels of tissue density from radiolucent to radiopaque:
Fat, water, bone, & air
Air, fat, water, bone
When two or more images are placed over each other in the frame
Superimposition
Why is superimposition a problem in radiography?
We lose differentiation between the two bones
Anterior to posterior view and posterior to anterior view are ____ plane views
Frontal
Lateral views are ___ plane views
Sagittal
The structures that are closest to the film plate are the (most/less) clearly imaged on the film and the structures that are further away from the film will appear (more/less) clear.
Most; less
Xrays are used to look for
Fractures
Quality of bone mineralization
Alignment of joints
DJD (Degenerative joint disease)
What are the ABCs of evaluation?
A - Alignment
