65-90 kVp
During the AP Abdomen the patient is positioned _____ when using the table?
Supine
The tough fibrous connective tissues that attach muscles to bone?
Tendons
What is the process by which a neutral atom or molecule acquires a positive or negative charge?
Ionization
Most important procedural factor that affects image contrast?
kVp
What is the kVp range used in a knee exam?
50-70kVp
During the AP Lower Ribs view, the bottom of the IR is positioned where on the patient?
Iliac Crest
The Medical and anatomical name for the big toe?

What are the 3 possible effects of reproductive organs exposed to radiation?
Cancer, Infertility, Genetic Effects
Grids
What is the kVp ranger used in a Humerus exam?
55-70kVp
During the Lateral T-spine view, the central ray is perpendicular and directed where?
3 to 4 inches below the jugular notch
On the Humerus this is situated distal to the greater and lesser tubercles and proximal to the deltoid tuberosity.
Surgical Neck
This is the degree to which a cell, tissue, organ, or organism is susceptible to the damaging effects of radiation.
Radiosensitivity
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
What is the mAs range used for a Caldwell/Townes exam of the skull?
25-35mAs
This alignment is used for the correct extension of the neck during PA axial (Caldwell) view of the Skull.
OML
Located on the proximal femur, between the femoral head and the intertrochanteric line/lesser trochanter.
Femoral Neck
____ are more sensitive to radiation due to their increased number of reproductive tissue.
Women
Condition that resulting in excessive fluid accumulation in abdominal cavity. Results in more uniform absorption = lower image contrast.
Ascites
What is the mAs used in a Scapula-Y view?
40mAs
During the AP pelvis you will rotate internally the axis of the feet and lower limbs how many degrees
15-20 Degrees
This bone is made up of 3 to 5 fused rudimentary vertebrae. Located at the base of the spine.
Coccyx
This law defines why younger people or developing embryos are more at risk from radiation exposure.
Law of Bergonie and Tribondeau
