Cards

Term
Anatomical Position
Definition
that of the human body standing erect with palms turned forward, used as the position of reference in designating the site or direction of structures of the body.
Term
Abduct
Definition
to draw away from the median plane, or (the digits) from the axial line of a limb
Term
Adduct
Definition
to draw toward the median plane or (in the digits) toward the axial line of a limb
Term
Inferior
Definition
situated below, or directed downward; in anatomy, used in reference to the lower surface of a structure, or to the lower of two (or more) similar structures.
Term
Medial
Definition
situated toward the median plane or midline of the body or a structure.
Term
Lateral
Definition
denoting a position farther from the median plane or midline of the body or a structure.
Term
Oblique
Definition
Situated in a slanting position; not transverse or longitudinal.
Term
Proximal
Definition
nearest to a point of reference, as to a center or median line or to the point of attachment or origin.
Term
Distal
Definition
Anatomically located far from a point of reference, such as an origin or a point of attachment.
Term
Projection
Definition
the orientation of a radiographic machine in relation to the body or a body part.
Term
Position
Definition
a bodily posture or attitude.
Term
Extension
Definition
the bringing of the members of a limb into or toward a straight condition.
Term
Flexion
Definition
the act of bending or the condition of being bent.
Term
Coronal plane
Definition
A vertical plane at right angles to a sagittal plane, dividing the body into anterior and posterior portions.
Term
Mid-coronal plane
Definition
the mid-coronal plane would transect a standing body into two halves (front and back, or anterior and posterior) in an imaginary line that cuts through both shoulders.
Term
Mid-sagittal or median plane
Definition
one passing longitudinally through the middle of the body from front to back, dividing it into right and left halves.
Term
sagittal plane
Definition
vertical planes passing through the body parallel to the median plane (or to the sagittal suture), dividing the body into left and right portions.
Term
caudal
Definition
situated more toward the cauda, or tail, than some specified reference point; toward the inferior (in humans) or posterior (in animals) end of the body.
Term
cephalic
Definition
pertaining to the head, or to the head end of the body
Term
superior
Definition
situated above, or directed upward
Term
supinate
Definition
assume or place in a supine position.
Term
pronate
Definition
To turn or rotate a limb so that the inner surface faces down or back.
Term
longitudinal
Definition
Running in the direction of the long axis of the body or any of its part
Term
transverse
Definition
extending from side to side; at right angles to the long axis.
Term
align
Definition
Place or arrange (things) in a straight line.
Term
artifact
Definition
any artificial (man-made) product; anything not naturally present, but introduced by some external source.
Term
cortical outline -
Definition
white lines
Term
contrast
Definition
radiographic contrast describes the differences in photographic density in a radiograph
Term
density
Definition
Radiographic density is the logarithm of two measurements: the intensity of light incident on the film (I0) and the intensity of light transmitted through the film (It).
Term
detail
Definition
resolution
Term
deviate
Definition
turning away or aside from a normal course.
Term
distortion
Definition
deviation of an image from the true outline or shape of an object or structure.
Term
elevate
Definition
To move (something) to a higher place or position from a lower one; lift.
Term
elongate
Definition
To make or grow longer.
Term
foreshorten
Definition
Portray or show (an object or view) as closer than it is or as having less depth or distance, as an effect of perspective or the angle.
Term
magnification
Definition
the ratio of apparent (image) size to real size.
Term
object to image distance
Definition
The distance between the subject and the IR
Term
Quantum mottle
Definition
an effect observed in radiographic imaging when the dose of radiation used is reduced to a level at which individual quantum effects can be seen.
Term
Recorded detail
Definition
- the sharpness of structural lines as recorded on a radiograph.
Term
Radiolucent
Definition
- permitting the passage of radiant energy, such as x-rays, with little attenuation, the representative areas appearing dark on the exposed film.
Term
radiopaque
Definition
- Relatively impenetrable by x-rays or other forms of radiation.
Term
resolution
Definition
- a measure of the fineness of detail that can be discerned in an image.
Term
scatter radiation
Definition
- Radiation that has been deflected from its path by impact during its passage through matter
Term
source to image distance
Definition
- the source to image-receptor distance (SID) is a measurement of the distance between the radiation source and the radiation detector.
Term
source to object distance
Definition
SID - OID
Term
superimpose
Definition
The ability to see two similar images superimposed but not mentally fused.
Term
symmetrical
Definition
equally on both sides.
Term
trabecular pattern
Definition
an irregular meshwork of stress and stress-related struts within a cancellous bone.
