A(n) ________ is an image of a patients anatomic part(s) as produced
by the actions of x-rays on an image receptor.
radiograph
The ________ is the aspect of an x-ray beam that has the least
divergence (unless there is angulation)
central ray
An upright position with the arms abducted, palms forward, and head
and feet directed straight ahead describes the ____________ position.
anatomic
The vertical plane that divides the body into equal right and left
parts is the __________ plane.
midsagittal/medial
The vertical plane that divides the body into equal anterior and
posterior parts is the ________ plane.
midcoronal
A plane taken at right angles along any point of the longitudinal
axis of the body is the ________ plane.
transverse/axial
True or False:
The base plane of the skull is a plane located between the
infraorbital margin of the orbit and the superior margin of the
external auditory meatus.
TRUE
True or False:
The Frankfort horizontal plane is also referred to as
the midcoronal plane.
FALSE
The direction or path of the central ray defines what positioning term:
Projection
The positioning term that describes the general and specific body
position is:
position
True or False:
Oblique and lateral positions are described according to the side of
the body closest to the image receptor.
TRUE
True or False:
Decubitus positions always use a horizontal beam.
TRUE
What is the name of the position in which the body is turned 90
degrees from a true anteroposterior (AP) or posteroanterior (PA) projection?
Lateral Position
A patient is erect with the back to the image receptor. The left side
of the body is turned 45 degrees toward the image receptor. What is
this position?
Left Posterior Oblique (LPO)
A patient is recumbent facing the image receptor. The right side of
the body is turned 15 degrees toward the image receptor. What is this position?
Right Anterior Oblique (RAO)
The patient is lying on his or her back. The x-ray beam is directed
horizontally and enters the right side of the body and exits the left
side of the body. An image receptor is placed against the left side of
the patient. Which specific position has been used?
Dorsal Decubitus (left lateral)
The patient is erect with the right side of the body against the
image receptor. The x-ray beam enters the left side of the body and
exits the right side of the body. Which specific position has been performed?
Right Lateral
A patient is lying on the left side on a cart. The x-ray beam is
directed horizontally and enters the posterior surface and exits the
anterior surface. The image receptor is against the anterior surface.
Which specific position has been performed?
Left Lateral Decubitus (PA)
Palm of hand
Palmar
laying on the back facing upward
Supine
An upright position
Erect
Laying down in any position
Recumbent
Front half of the patient
Anterior
Top or anterior surface of the foot
Dorsum pedis
Position in which head is higher than the feet
Fowler's
Posterior aspect of the foot
Plantar
Position in which head is lower than the feet
Trendelenburg
Back half of the patient
Posterior
What is the name of the projection in which the central ray enters
the anterior surface and exits the posterior surface?
anterior posterior (AP)
A projection using a CR angle of 10 degrees or more directed parallel
along the long axis of the body or body part is termed a/an _______ projection.
axial
The specific position that demonstrates the apices of the lungs,
without superimposition of the clavicles, is termed a/an ________ position.
(apical) lordotic
True or False:
Radiographic "view" is not a correct positioning term used
in the United States.
TRUE
True or False:
The term varus describes the bending of a part outward.
FALSE
Position or Projection:
Anteroposterior
Projection
Position or Projection:
Prone
