Term 1 of 124
What position for the lateral projection of the foot?
the ankle should be dorsiflexed so that the long axis of the foot is perpendicular to the tibia
the toes should be pointed downwards to visualize the arch of the foot
the foot should be rotated laterally to show the heel clearly
the base of the third metatarsal
Term 2 of 124
Structure that serves as a passageway for spinal cord to exit skull:
foramen rotundum
spinous process
foramen magnum
foramen ovale
Term 3 of 124
SI radiation unit to express radiation intensity in the air is:
roentgen equivalent man (rem)
entrance skin dose (esd)
kvp
coulomb/kilogram (c/kg)
,Term 4 of 124
Radiation that leaves the x-ray tube is called:
scatter
erythema
primary beam
leakage
Definition 5 of 124
Pronation
Three prinicple methods used to protect lmrts from unnecessary radiation exposure
What position for the lateral projection of the foot?
The way your foot rolls inward for impact distribution upon landing
Primary cause of scatter radiation:
Term 6 of 124
The anode heel effect is caused by:
The increased intensity of x-rays at the center of the beam
X-ray absorption within the anode which results in the image being lighter on anode end,
darker on cathode end
The effect of using a higher dose of radiation on image quality
The scattering of x-rays due to patient movement during imaging
,Term 7 of 124
X-ray beam has photons with different energies can be described as:
Homogenous
Pronation
Elongation
Heterogenous
Term 8 of 124
The measure of the radiation dose that is absorbed (measured in milli-gray) by the skin as it
reaches the patient:
Equivalent dose (eqd)
Entrance Skin Dose (ESD)
Genetically Significant Dose (gsd)
Effective dose (efd)
Term 9 of 124
Determine the cumulative effective dose (CumEfD) to the whole body of an occupationally
exposed person who is 27 years old:
540 msv (age x 20) (this would be 27 x 20 =540 msv)
135 msv (age x 5) (this would be 27 x 5 =135 msv)
270 mSv (age x 10) (this would be 27 x 10 =270 mSv)
90 msv (age x 3) (this would be 27 x 3 =90 msv)
, Term 10 of 124
Which bones are in the hindfoot portion of the foot?
Humerus, Femur
Tibia, Fibula
Radius, Ulna
Calcaneous, Talus
Term 11 of 124
What is the name of the upper portion of the lung?
Hilum (hilus)
Entrance skin dose (esd)
Long scale
Apex (apices)
Term 12 of 124
Greatest portion of x-ray beam is made up of?
Compton effect
Bremsstrahlung radiation
Characteristic radiation
Photoelectric
