Question

Quizplus · Accepted Answer

Ed C. Jerman is known as the father of radiologic technology.

Answer: B
 Arthur Fuchs was a pioneer in developing automatic exposure control systems.

Answer: F
 AEC stands for automatic exposure control and is a system that automatically adjusts the exposure factors based on the size and density of the body part being imaged.

Answer: H
 A phantom is a device used to simulate the characteristics of human tissue in order to test imaging equipment and exposure techniques.

Answer: E
 Fixed kVp systems use a constant kVp setting for all imaging studies and adjust the mA and exposure time to achieve the desired image quality.

Answer: I
 Fixed kVp systems use a constant kVp setting for all imaging studies and adjust the mA and exposure time to achieve the desired image quality.

Answer: D
 Variable kVp systems allow the operator to adjust the kVp settings based on the body part and the patient's size and shape.

Answer: K
 The 15% rule states that a 15% increase in kVp will result in a doubling of the exposure to the image receptor.

Answer: L
 The 2 kVp rule states that a change of 2 kVp is equivalent to a change in mAs by a factor of 2.
