200

Most important procedural factor that affects image contrast?

kVp

200

What is the kVp range used in a knee exam?

50-70kVp

200

During the AP Lower Ribs view, the bottom of the IR is positioned where on the patient?

Iliac Crest

200

The Medical and anatomical name for the big toe?

Hallux

200

What are the 3 possible effects of reproductive organs exposed to radiation?

Cancer, Infertility, Genetic Effects

300
This has a huge impact on the am ount of scatter that reaches the IR. Used to "clean up"an image and increase contrast.

Grids

300

What is the kVp ranger used in a Humerus exam?

55-70kVp

300

During the Lateral T-spine view, the central ray is perpendicular and directed where?

3 to 4 inches below the jugular notch

300

On the Humerus this is situated distal to the greater and lesser tubercles and proximal to the deltoid tuberosity.

Surgical Neck

300

This is the degree to which a cell, tissue, organ, or organism is susceptible to the damaging effects of radiation.

Radiosensitivity

400

A technique used to improve contrast by reducing the amount of scatter reaching the IR. Can be used instead of a Grid to reduce noise/scatter in an image.

Air Gap Effect

400

What is the mAs range used for a Caldwell/Townes exam of the skull?

25-35mAs

400

This alignment is used for the correct extension of the neck during PA axial (Caldwell) view of the Skull.

OML

400

Located on the proximal femur, between the femoral head and the intertrochanteric line/lesser trochanter.

Femoral Neck

400

____ are more sensitive to radiation due to their increased number of reproductive tissue.

Women

500

Condition that resulting in excessive fluid accumulation in abdominal cavity. Results in more uniform absorption = lower image contrast.

Ascites

500

What is the mAs used in a Scapula-Y view?

40mAs

500

During the AP pelvis you will rotate internally the axis of the feet and lower limbs how many degrees

15-20 Degrees

500

This bone is made up of 3 to 5 fused rudimentary vertebrae. Located at the base of the spine. 

Coccyx

500

This law defines why younger people or developing embryos are more at risk from radiation exposure.

Law of Bergonie and Tribondeau
