Question

Quizplus · Accepted Answer

The term "average gradient" is used to calculate the slope of the H and D curve.

Answer: E
 "Short scale contrast" refers to the ability to distinguish small differences in contrast between adjacent structures on an image.

Answer: F
 "High contrast" refers to an image with a small range of grayscale values, resulting in a stark difference between black and white.

Answer: G
 "Photoelectric interactions" occur when an incoming photon interacts with an inner shell electron in an atom, resulting in ionization and the emission of characteristic radiation.

Answer: H
 "Subject contrast" refers to the range of densities or attenuation coefficients of structures within the patient that affect the appearance of an image.

Answer: D
 "Low contrast" refers to an image with a large range of grayscale values, resulting in a subtle difference between black and white.

Answer: C
 "Compton interactions" occur when an incoming photon interacts with an outer shell electron in an atom, resulting in ionization and the scattering of the photon in a different direction.

Answer: B
 "Long scale contrast" refers to the ability to distinguish large differences in contrast between adjacent structures on an image.
