Technical Considerations Review

Which of the following parameters still apply to radiographic image formation in both CR and DR units?

• SID

• OID

• kVp

• All of the above

What does the term "remnant beam" refer to?

• The initial x-ray beam

• The beam that exposes the IR

• The scattered x-ray beam

• None of the above

Higher kVp values in digital imaging are beneficial due to:

• Increased patient dose

• Higher noise levels

• Higher k-edge of the detector

• Lower image quality

What is the main consequence of using too low mAs values?

• Excessive noise

• High contrast

• Low patient dose

• None of the above

Which of the following can lead to detector saturation?

• Excessive mAs

• Low kVp

• High SID

• None of the above

What is an Exposure Indicator # (EI#)?

• A method to assess patient size

• A numerical parameter for monitoring radiation exposure to the IR

• A measure of image quality

• None of the above

What is the primary goal of exposure technique systems?

• To increase patient dose

• To reduce image quality

• To ensure consistent image quality

• To increase noise levels

The fixed kVp system primarily adjusts mAs based on:

• Patient weight

• Patient age

• Optimum kVp

• None of the above

What is the recommended change in mAs for every 5 cm change in thickness?

• 10%

• 20%

• 30%

• 40%

In the variable kVp system, what is the base kVp typically set at?

• 50 kVp

• 60 kVp

• 30 kVp

• 70 kVp
