RAD 111 Module 1 Review

A patient is placed in a recumbent position facing downward. The left side of the body is turned 30 degrees toward the IR. What specific position has been performed?

• LAO

• Left lateral decubitus

• LPO

• RAO

An elbow projection is taken with the posterior surface placed against the IR. The elbow is rotated 20 degrees externally. Which specific projection has been performed?

• PA oblique with medial rotation

• PA oblique with lateral rotation

• AP oblique with medial rotation

• AP oblique with lateral rotation

Which of the following positioning routines should be performed for a chest study?

• PA and lateral projections

• PA, oblique and lateral projections

• AP. PA, and lateral projections

• PA, RAO, and LAO projections

All of the following are primary image-quality factors except:

• Contrast

• Distortion

• Density

• Kilovoltage

A radiograph of the elbow is overexposed. The technologist want to adjust kV rather than mAs for the repeat exposure. The original analog exposure factors were 70 kV and 5 mAs. Which of the following kV settings would reduce radiographic density by one-half?

• 80 kV

• 66 kV

• 60 kv

• 56 kV

Which pair of terms do not belong together?

• Cephalad - Caudad

• Superior - Inferior

• Medial - Distal

• Ipsilateral - Contralateral

A patient has fallen on ice and has a possible proximal femur fracture. What is the minimum number of projections that should be taken for this patient?

• One

• Two

• Three

• Five

Highly complex mathematical formulas used in creating the digital image are termed:

• digital reconstructions

• bit processing matrices

• digital displays

• algorithms

The recorded sharpness of structures on the image is the definition for:

• spatial resolution

• SNR

• equalization

• bit depth

What is the primary purpose of x-ray tube filtration?

• absorb lower energy x-rays

• reduce the x-ray intensity

• increase quantity of the x-ray photons

• all of the above
