Question 1

Which type of graph is used to document the results from the sensitometric testing of film processors?&#10;A)Control chart&#10;B)Histogram&#10;C)Pareto chart&#10;D)Fishbone chart

Accepted Answer

A control chart indicating upper and lower accepted limits is used to document the results of sensitometric testing.

Question 2

B + F is measured in the&#10;A)clear area of the film.&#10;B)lightest step in the pattern.&#10;C)medium step in the pattern.&#10;D)darkest step in the pattern.

Accepted Answer

The base + fog optical density value is measured in the clear area of a film during sensitometric testing.

Question 3

Processing time should not vary by more than ____ of the manufacturer's recommendation.&#10;A)&#177;1% to 2%&#10;B)&#177;2% to 3%&#10;C)&#177;5% to 7%&#10;D)&#177;10% to 15%

Accepted Answer

Processing time should not vary by more than ±2% to 3% of the manufacturer's recommendation. This ensures consistency and quality control in the manufacturing process. Any significant variation can lead to defects or inconsistencies in the final product.

Question 4

Which of the following devices is used to create a 21-step wedge pattern on a film during sensitometric testing?&#10;A)Densitometer&#10;B)Sensitometer&#10;C)Film duplicator&#10;D)Ultraviolet light

Accepted Answer

A sensitometer is a device used in sensitometric testing to produce a 21-step wedge pattern on a film. This pattern is used to measure the film's sensitivity to light and to determine its proper exposure and development time. A densitometer is used to measure the optical density of the pattern, but it does not create the pattern itself. A film duplicator is used to make copies of a film, and ultraviolet light is not typically used in sensitometric testing.

Question 5

Which of the following is acceptable for a variation in the B + F (base + fog) value during sensitometric testing in radiography?&#10;A)&#177;0.01&#10;B)&#177;0.03&#10;C)&#177;0.05&#10;D)&#177;0.10

Accepted Answer

During sensitometric testing in radiography, a variation of ±0.05 in the B + F (base + fog) values is considered acceptable. This level of variation allows for minor differences in equipment performance and environmental factors, while still maintaining reliable image quality. Options A and B are too restrictive, while option D is too lenient and may result in unacceptable image quality.

Question 6

Which of the following is acceptable for variation in the mid-density indicator during sensitometric testing in radiography?&#10;A)&#177;0.05&#10;B)&#177;0.10&#10;C)&#177;0.15&#10;D)&#177;0.20

Accepted Answer

The answer of Which of the following is acceptable for...

Question 7

Replenishment rates should not vary by more than ____ of the manufacturer's recommendation.&#10;A)&#177;1%&#10;B)&#177;2%&#10;C)&#177;5%&#10;D)&#177;10%

Accepted Answer

Replenishment rates that vary by more than 5% of the manufacturer's recommendation might result in overstocking or understocking of inventory, causing potential losses for the business. Therefore, it is essential to maintain replenishment rates within a 5% deviation from the manufacturer's recommendation. A variation within this range considers the dynamic inventory requirements and ensures an optimum balance between stock levels and demand.

Question 8

Variation during sensitometric testing that occurs because of the test film being run in different parts of the feed tray is called&#10;A)bromide drag.&#10;B)locational effect.&#10;C)time of day variability.&#10;D)bias.

Accepted Answer

Locational effect refers to the variation in sensitometric testing that occurs because of the test film being run in different parts of the feed tray. Bromide drag refers to the distortion of image caused by unequal distribution of developer and fixer solutions. Time of day variability and bias are not related to the variation in sensitometric testing caused by the test film position in the feed tray.

Question 9

Which of the following is obtained by subtracting the Dm&#7522;n from the Dm&#8336;&#8339;?&#10;A)Speed indicator&#10;B)Mid-density indicator&#10;C)High-density indicator&#10;D)Contrast indicator

Accepted Answer

The contrast indicator is obtained by subtracting the minimum density (Dmᵢn) from the maximum density (Dmₐₓ), which measures the range of densities in an image.

Question 10

Which of the following would be the acceptable temperature variation allowable in automatic film processor quality control?&#10;A)&#177;0.5&#176; F&#10;B)&#177;1&#176; F&#10;C)&#177;1.5&#176; F&#10;D)&#177;2&#176; F

Accepted Answer

The acceptable temperature variation in automatic film processor quality control is typically ±0.5° F to ensure consistent film development and image quality.
