Basics of Radiographic Exposure Factors

What does 'kVp' stand for?

• Kilo Voltage Peak

• Kilovolt Power

• Kinetic Voltage Peak

• Kinetic Volt Power

What does 'mAs' represent in radiographic exposure?

• Milliamps per second

• Milliampere-seconds

• Milliampere-shots

• Milliamps per shot

What is the primary function of 'AEC' in digital imaging?

• Controls image contrast

• Measures patient dose

• Manually adjusts exposure

• Automatically selects exposure

What does 'mAs' determine in an X-ray beam?

• Beam contrast

• Beam energy

• Beam quantity

• Beam quality

What is the relationship between mAs and beam quantity?

• Inverse

• Logarithmic

• Linear

• Exponential

What happens to image noise when you decrease kVp?

• Increases noise

• Has no effect

• Decreases noise

• there is no such thing as image noise

What is the effect of a lower kVp on image contrast?

• lower contrast

• higher contrast

• there is no such thing as image contrast

• No effect

What is the 15% rule in radiographic exposure?

• A 15% increase in kvp decreases the exposure

• A 15% increase in kvp halves the exposure

• A 15% increase in kvp doubles the exposure

• A 15% increase in kvp has no effect

What does 'SNR' stand for?

• Signal Noise Rate

• Signal to Noise Rate

• Signal to Noise Ratio

• Signal Noise Ratio

What happens to the image if the exposure factors are set too low?

• Low noise

• High contrast

• Underexposed

• Overexposed
