Concepts Of Rad Image Quality Flashcards
Is the exactness of representation of the patient’s anatomy on a radiographic image.
RADIOGRAPHIC IMAGE QUALITY
Are required so that technologists can make accurate diagnoses.
HIGH-QUALITY IMAGES
The 3 Major Interrelated Categories of Radiographic Quality
- FILM FACTORS
- GEOMETRIC FACTORS
- SUBJECT FACTORS
What are the 4 Characteristics Curve of a Film Factors
- DENSITY
- CONTRAST
- SPEED
- LATITUDE
2 Processes of a Film Factors
- TIME
- TEMPERATURE
3 Geometric Factors
- DISTORTION
- MAGNIFICATION
- BLUR
The 3 Contrast of a Subject Factors
- THICKNESS
- DENSITY
- ATOMIC NUMBER
The 3 Interrelated Characteristics of Radiographic Quality
- RESOLUTION
- NOISE
- SPEED
The ability to image two separate objects and visually distinguish one from the other.
RESOLUTION
Refers to the ability to image small objects that have high subject contrast.
SPATIAL RESOLUTION
Screen Film Radiography has excellent spatial resolution. TRUE OR FALSE?
TRUE
The ability to distinguish anatomical structure of similar subject contrast such as liver-spleen and gray matter- white matter
CONTRAST RESOLUTION
Sometimes are used instead of spatial resolution and contrast resolution.
RECORDED DETAIL AND DETAIL
These terms refer to the degree of sharpness of structural lines on a radiograph
RECORDED DETAIL AND DETAIL
Refers to the ability to visualize recorded detail when image contrast and optical density are optimized
VISIBILITY OF DETAIL
